While children should receive HBV ( Hepatitis B vaccine) and BCG (Bacillus Calmette–Guérin vaccine for tuberculosis) at birth, along with DTaP (Diphtheria, tetanus, and acellular pertussis vaccine), Hib (Haemophilus influenza type b vaccine), IPV (Inactivated poliovirus vaccine) and PCV (Pneumococcal conjugate vaccines) until they are about eighteen months old, there are many  vaccinations for adults. Why do adults need vaccinations?

Immunity to some diseases can fade over time, which is the main reason  adults need to be re-vaccinated. There are now some very effective vaccines that adults can take to protect themselves from new strains of viruses and bacteria.

What are some adult vaccinations? Some of the common vaccinations taken by adults include the flu (influenza), Human papilloma virus (HPV), Varicella (chicken pox), Herpes Zoster (shingles), Pneumococcal, Hepatitis A and B, Tetanus, Typhoid and Meningococcal vaccines. immunisation Why do some countries require vaccinations in visitor visa applications?

For example, vaccine-preventable diseases that are rare in Malaysia, such as yellow fever, can still be found in other parts of the world. Another example of mandatory travel vaccination can be found in Saudi Arabia; the country  requires proof of the vaccination for meningococcal meningitis for visitors arriving for the Hajj and Umrah pilgrimages.
