Vaccines play a crucial role in preventing infectious diseases and protecting our health. They have been successful in eradicating deadly diseases and reducing the burden of illnesses worldwide. However, there are still some misconceptions surrounding vaccines that need to be addressed. In this blog, we will explore the essential vaccines and boosters that every adult should have.

What are Vaccines?

Vaccines are a crucial tool in preventing and controlling infectious diseases. They work by stimulating the immune system to recognise and fight specific pathogens. Vaccines contain small amounts of either weakened or inactivated microorganisms, or parts of microorganisms, that help the body develop immunity without causing severe illness.

Some of the common types of vaccines include:

• Live attenuated vaccines: These contain weakened versions of live microorganisms that can still replicate but cause no or mild symptoms. Examples include the measles, mumps, and rubella (MMR) vaccine.
• Inactivated vaccines: These contain killed or inactivated microorganisms incapable of replication. Examples include the hepatitis B vaccine for adults.
• Subunit vaccines: These contain only specific antigens from the microorganism, not the whole organism. Examples include the tetanus vaccine.
• mRNA vaccines: These use a small piece of genetic material called messenger RNA to instruct cells to produce a harmless protein similar to the antigen found on the pathogen's surface.

Benefits of Vaccinations

The benefits of vaccinations are manifold.

• Personal protection: They provide personal protection, preventing individuals from contracting potentially severe and life-threatening diseases.
• Herd immunity: When a significant portion of the population is vaccinated, it creates a barrier that prevents the spread of infectious diseases, thereby safeguarding those who are unable to receive vaccinations, such as infants or individuals with weakened immune systems.

Recommended Vaccines for Adults

Let's know about the different types of vaccines essential for an adult.

1. Routine Vaccinations

While many people associate vaccines with childhood, it is important to remember that adults also need certain vaccinations to maintain their health and well-being. Here are some recommended vaccines for adults:

A. Tetanus, Diphtheria, Pertussis (Tdap) vaccine

Tdap vaccine protects against tetanus, diphtheria, and pertussis (whooping cough). Adults should receive a Tdap booster every 10 years to ensure ongoing protection.

B. Influenza vaccine

The flu can have serious complications for adults, especially those with chronic health conditions. An annual influenza vaccine is recommended for all adults to reduce the risk of getting the flu and its associated complications.

C. Human Papillomavirus (HPV) vaccine

HPV is a common sexually transmitted infection that can lead to various types of cancers. The HPV vaccine is recommended for both males and females up to the age of 26.

D. Measles, Mumps, Rubella (MMR) vaccine

If you haven't received the MMR vaccine in childhood or are unsure about your vaccination status, it is recommended to get vaccinated as an adult. Measles and mumps outbreaks can occur even in adults, so protecting yourself against these diseases is important.

2. Travel-related Vaccinations

In addition to routine vaccines, several vaccines are recommended for those travelling. Here are some of them:

A. Hepatitis A vaccine

Hepatitis A is a highly contagious liver infection that can be spread through contaminated food and water. Travellers to certain countries and individuals at increased risk, such as those with chronic liver disease or men who have sex with men, should consider getting the hepatitis A vaccine for adults.

B. Typhoid fever vaccine

Typhoid fever is a bacterial infection that is commonly transmitted through contaminated food and water. It is more prevalent in developing countries. The typhoid fever vaccine is recommended for travellers to areas where typhoid is endemic or common.

C. Yellow fever vaccine

Yellow fever is a viral infection transmitted by mosquitoes. It is primarily found in tropical regions of Africa and South America. Travellers to these areas may require the yellow fever vaccine as a condition of entry or to protect themselves from the disease.

Occupational Vaccinations

A. Hepatitis B vaccine for healthcare professionals

It is recommended that all healthcare personnel receive the Hepatitis B vaccine as they are at high risk of developing the infection from the patients. This vaccine is given in a series of three doses and provides long-term protection against the virus.

B. Rabies vaccine for veterinarians and animal handlers

Veterinarians and animal handlers face the risk of being bitten or scratched by animals, which increases their chances of contracting rabies. The rabies vaccine is crucial for these professionals to prevent the deadly viral infection. It is administered in a series of shots and helps build immunity against rabies.

Boosters and Additional Vaccines

In this section, we will delve into some boosters and additional vaccines recommended for adults.

1. Tetanus and Diphtheria Boosters

The tetanus booster shot for adults is recommended every 10 years to maintain immunity against this deadly infection. It is especially important if you have experienced a deep or dirty wound, as tetanus bacteria thrive in such environments. Additionally, if you can't recall the last time you received a tetanus booster, it's wise to get one to ensure continued protection.

Combination boosters, such as the Tdap (tetanus, diphtheria, and pertussis) or Td (tetanus and diphtheria), are also available for adults. These vaccines not only protect against tetanus and diphtheria but also against pertussis (whooping cough).

2. Pneumococcal Vaccine

The pneumococcal vaccine is an essential vaccine for adults, as it helps protect against pneumonia, meningitis, and other pneumococcal diseases. The vaccine stimulates the immune system to produce antibodies against the bacteria called Streptococcus pneumoniae, which causes pneumococcal infections.

3. Shingles Vaccine

To prevent shingles and postherpetic neuralgia, an adult should get the shingles vaccine or the herpes zoster vaccine. This vaccine contains a weakened form of the varicella-zoster virus, which helps boost the immune system's ability to fight against the virus.

4. Meningococcal Vaccine

The meningococcal vaccine is recommended for adults who are at increased risk of exposure to the bacteria or who have certain medical conditions that put them at higher risk of developing meningococcal disease. This includes:

• Individuals with a damaged spleen or no spleen
• Those living in crowded settings such as college dormitories
• People travelling to areas where the disease is more common

The meningococcal vaccine protects against meningitis and septicemia.

Special Considerations and Recommendations

There are some vaccines that are highly recommended to the following people:

1. Vaccines for Pregnant Women

Pregnancy is a critical time for both the mother and the developing baby. Vaccination plays a crucial role in protecting pregnant women and their infants from preventable diseases. Some of these important vaccines include:

• Flu shot: Influenza can lead to severe complications in pregnant women. The flu vaccine is safe, and effective, and can protect both the mother and the baby from flu-related complications.
• Tdap: Tdap stands for Tetanus, Diphtheria, and Pertussis. The Tdap vaccine is given to pregnant women between 27 and 36 weeks of gestation to protect them from pertussis (whooping cough) and to pass on some immunity to their newborns.

2. Vaccines for Seniors

As we age, our immune system weakens, making seniors more susceptible to infections. To maintain optimal health, older adults must stay up-to-date with their vaccinations. Here are some key recommendations for vaccines in older adults:

• Influenza Vaccine: Older adults should receive an annual flu shot to protect against seasonal flu viruses.
• Pneumococcal Vaccine: Pneumonia is a serious infection that can lead to life-threatening complications in seniors. The pneumococcal vaccine helps protect against pneumococcal diseases, including pneumonia.
• Shingles Vaccine: Shingles is a painful rash caused by the varicella-zoster virus, the same virus that causes chickenpox. Seniors should consider getting the shingles vaccine to reduce the risk of developing this painful condition.

3. Vaccines for Individuals with Chronic Conditions

Individuals with chronic conditions, such as diabetes, heart disease, or lung disease, may have a weakened immune system, making them more susceptible to infections. Here are some special considerations for immunocompromised individuals:

• Influenza Vaccine: People with chronic conditions should receive an annual flu shot to protect against seasonal flu viruses.
• Pneumococcal Vaccine: Individuals with chronic conditions should receive the pneumococcal vaccine to protect against pneumonia and other pneumococcal diseases.

Are Vaccines Safe?

Vaccines have revolutionised healthcare by preventing serious diseases and saving millions of lives. However, there are concerns and misconceptions surrounding vaccine safety. It is important to address these concerns to ensure that individuals make informed decisions about their health. Let's debunk common myths about vaccine safety:

1. Myth: Vaccines cause autism.

Fact: Extensive research has shown no link between vaccines and autism. Multiple studies have debunked this myth, and leading scientific organizations agree that vaccines are safe.

2. Myth: Vaccines contain harmful ingredients.

Fact: Vaccines undergo rigorous testing to ensure safety. They may contain trace amounts of substances like formaldehyde or aluminium, but these quantities are minuscule and pose no harm to the body.

3. Myth: Natural immunity is better than vaccine-induced immunity.

Fact: While natural immunity can develop after infection, it comes at the risk of severe complications or even death. Vaccines offer a safer way to build immunity without the dangers associated with diseases.

What are the Side Effects of Vaccines?

Vaccine side effects are generally mild and temporary. They indicate that the immune system is responding appropriately to the vaccine. Common side effects include:

• Pain, redness, or swelling at the injection site
• Low-grade fever
• Fatigue or muscle aches

To manage these mild reactions:

• Apply a cold compress to reduce pain or swelling at the injection site.
