Immunization has been one of the essential measures to prevent diseases and hence saving millions of lives from vaccine-preventable diseases. While a lot of importance has been given
to childhood vaccination, adult immunization, which plays an equally vital role in preventing disease and reducing healthcare costs, is deemed less of a priority.
With the increase in age, the overall immunity weakens (called immunosenescence). This increases the susceptibility to certain infections and their complications. Also, mutations (changes in the genetic makeup) in some viruses mandates regular vaccination (example-Influenza). To add to this, there are some groups of adult patients who are at higher risk of infections, like patients on medications, for various diseases, which weaken the immune system; transplant recipients, patients with HIV infection etc.
Despite these, most immunization programs primarily focus on childhood vaccinations, leaving adults under-vaccinated and vulnerable to vaccine-preventable diseases. <2% of the
adult population gets vaccinated for influenza, pneumococcal, typhoid, and hepatitis B vaccines. This poor state is due to the lack of awareness and the absence of proper
government guidelines for the adult population in India.
Based on the risk factors for adults, the following vaccines are strongly recommended in India.
Influenza vaccine
Annual influenza vaccination is strongly recommended, particularly among high-risk groups
like the elderly and those with chronic illnesses.
Pneumococcal vaccination
Elderly, and adults with specific medical conditions like chronic like and heart problems, immunocompromised patients etc. Pneumonia remains a significant health concern in in these
and can be life threatening.
COVID-19 vaccination
The vaccination program for COVID-19 in our country has been a success. All should follow the updated government guidelines and should get themselves vaccinated.
Tetanus, diphtheria, and pertussis
Booster of this vaccine is recommended every 10 years. This booster strategy for adults, can ensure ongoing protection against these diseases.
Zoster (shingles) vaccine
This vaccine is shown to decrease the incidence as well as complications associated with Herpes zoster, and is recommended in adults more than 50 years of age.
Hepatitis B
Everyone should take this vaccine to protect themselves from Hepatitis B, as this infection could lead to permanent liver damage and liver cancer. It should be prioritized for adults at
risk, especially health-care workers, and diabetics.
If you are an adult, we highly recommend scheduling an appointment for vaccination right away to protect your health.
