Really?
All the people at Johns Hopkins would disagree with you. And all vaccines only temporarily increase immune response.
Animals need rabies vaccine boosters
People need MMR and tetanus boosters
According to experts, booster shots are common. An additional dose can help bolster immunity against COVID-19.

According to
Jason C. Gallagher, PharmD, FCCP, FIDP, FIDSA, BCPS, clinical professor at Temple University’s School of Pharmacy and clinical specialist in infectious diseases, boosters are common.
“Most vaccines that are given in the U.S. require several doses to render immunity,” Gallagher tells Verywell. “I like to think of [a COVID-19 vaccine booster] as the third dose of a multi-dose series.”
While boosters are common, whether they’re necessary largely depends on the type of vaccine,
Jeffrey Langland, PhD, virologist and professor at Southwest College of Naturopathic Medicine, tells Verywell.
“Most vaccines that do not contain a live, attenuated (weakened) virus, typically require multiple doses or boosters,” Langland says.
One dose of some live vaccines can offer you a lifetime of protection against disease.3 Other live vaccines may require two doses, like the measles, mumps, and rubella (MMR) and chickenpox vaccines. Children typically get their first dose at 12–15 months old and their second (and final) dose between age 4–6.4
But other types, like inactivated vaccines, will need several doses over time to remain effective. Boosters are currently recommended for several vaccines—chances are you’ve likely received one in your lifetime.
