With the availability of the Covid-19 vaccine, there is hesitancy among around 13 percent of Americans, according to a new survey by the public religion research institute.

Even some people involved in health like ex-Pfizer scientist Michael Yeadon have expressed some hesitancy over vaccines.

“There is absolutely no need for vaccines to extinguish the pandemic. I’ve never heard such nonsense talked about vaccines. You do not vaccinate people who aren’t at risk from a disease,” Yeadon said.

 But, according to various health experts, the claims of ineffectiveness are not accurate and the hesitancy is unjustified. In a joint statement about the effectiveness of the Covid vaccine, the heads of various United States agencies and institutions affirmed its effectiveness. 

“The Covid-19 vaccines authorized in the United States continue to be remarkably effective in reducing the risk of severe disease, hospitalization, and death, even against the widely circulating Delta variant.”

Studies testing the effectiveness of vaccines in real-world conditions have shown that the vaccines have been extremely effective. Most of the data regarding the effectiveness of vaccines is about the Moderna and Pfizer vaccines, due to them being available longer but more and more studies will continue to come out about the effectiveness of other vaccines like the Johnson and Johnson vaccine. 

Studies have also shown that while receiving one dose of the vaccine provides some protection against Covid-19, they have concluded that getting two doses of the vaccine is far more effective at protecting people from the virus.

If someone is concerned about the variants the CDC outlines, vaccines can help reduce the effects of these variants and are the best defense against the variants and their potential side effects.
