WHO observes “World Immunization Week” ( Apr. 24-30 ) to promote Public Health Security

PARTHA ROY, KOLKATA: World Immunization Week, observed annually from April 24 to 30 under the leadership of the World Health Organization (WHO), highlights vaccines as one of the most effective tools in public health. The 2026 theme, “For every generation, vaccines work”, emphasizes how immunization protects individuals across all age groups—from infants to the elderly. Over the past 50 years, vaccines have saved an estimated 154 million lives worldwide, averaging six lives every minute. Measles vaccination alone has accounted for nearly 94 million of these lives. Vaccines work by training the immune system to recognize and fight specific pathogens without causing illness. They include live attenuated (e.g., measles, oral polio), inactivated (e.g., injectable polio), toxoid (tetanus, diphtheria), subunit/conjugate (pneumococcal, HPV), and modern recombinant or mRNA types.

In India, the Universal Immunization Programme (UIP) primarily targets children, providing vaccines such as BCG (TB), pentavalent (diphtheria, pertussis, tetanus, hepatitis B, Hib), measles-rubella, rotavirus, and pneumococcal on a fixed schedule from birth through adolescence. Pregnant women receive tetanus toxoid to protect newborns. While childhood immunization has significantly reduced infant mortality, adult vaccination remains neglected. Over 25% of deaths in India are linked to infectious diseases. Childhood immunity often wanes over time, and adults face new risks due to age, lifestyle, travel, occupation, or chronic conditions like diabetes and heart disease, which are rising rapidly.

A life-course approach to immunization is therefore essential. •For young adults (18–45 years): HPV vaccine (especially for women up to 45 and select men) prevents cervical and other cancers; hepatitis B is crucial for healthcare workers and high-risk groups; Tdap boosters every 10 years protect against tetanus, diphtheria, and pertussis. •Middle-aged adults (30–50 years): Annual influenza and typhoid vaccines are beneficial, particularly for those who travel frequently or eat out often. •Seniors (above 50–65 years): Pneumococcal vaccine prevents severe pneumonia, shingles vaccine reduces painful nerve complications, and flu/pneumococcal shots lower hospitalization risks in people with comorbidities.

Pregnant women should receive Tdap and flu vaccines. Adult vaccination coverage in India remains very low—often below 2% for flu, pneumococcal, and hepatitis B vaccines. With nearly 23% of the population projected to be over 50 in the coming decades, expanding adult immunization is critical to reduce morbidity and healthcare burden. Vaccines form the foundation of protection, but they can be complemented by natural immunity-boosting practices rooted in Ayurveda. Nutrient-rich foods such as amla (rich in vitamin C), turmeric (curcumin), ginger, garlic, citrus fruits, nuts, seeds, and leafy greens help strengthen immunity. Traditional remedies like daily chyawanprash, golden turmeric milk (haldi doodh), and herbal kadha (with tulsi, ginger, cinnamon, and black pepper) are widely used.

Herbs such as tulsi, giloy, and ashwagandha act as adaptogens that support immune modulation and stress reduction. Ayurvedic lifestyle principles—dinacharya (daily routines), yoga, adequate sleep, balanced digestion (agni), and seasonal diet—further enhance resilience. Integrating modern vaccines with time-tested Ayurvedic wisdom offers a holistic approach to health. World Immunization Week 2026 reminds us that vaccines work for every generation. Sustained awareness, improved access, and healthy living practices together can build healthier families and communities. Consult your healthcare provider for a personalized immunization schedule and combine scientific vaccines with nature’s supportive remedies for comprehensive protection.
