The COVID-19 vaccines, are tools to help us end the pandemic, as soon as possible. There are three main COVID vaccines. Pfizer, Moderna, and J&J. With Pfizer and Moderna requiring two doses to be fully vaccinated, while only requiring one dose for the J&J. However, only having a overall efficacy rate of 72%, while the other two vaccines consisting of a 95% efficacy rate(Moderna), with Pfizer also having the same overall efficacy rate.
With J&J having such a big difference in efficacy rates with the other two vaccines, how safe are recipients of the J&J vaccine? With many health officials stating that they believe that the J&J vaccine should also be a two dose vaccine. “J&J is a very good vaccine. I also believe it’s probably a two-shot vaccine,” said Dr. Ashish Jha, dean of the Brown University School of Public Health. “It’s really urgent that people get that second shot pretty quickly. With recommendations of getting the booster shot of the J&J vaccine as soon as its available. “Probably one is not enough. And everybody who has had one needs a second one two months after the first. They are going to get full protection if they do that,” he said.
Research found stated that the J&J efficacy decreased from 88% in March to 3% in August, while the Moderna and Pfizer vaccines only dropped around 30-40% from 91-92% respectively. With such a substantial drop, are recipients of the J&J vaccine really save from the virus, with only one dose? Even with the recent introduction of the more deadly delta variant, J&J vaccines are definitely are not as effective as the other two vaccines, with just one more dose, J&J may have similar or even better efficacy rates than the Moderna and Pfizer vaccines.
With just a big difference between the three vaccines, the Moderna and Pfizer vaccines are superior options compared to the J&J vaccines. With two doses, J&J would clearly be a viable options when compared with the other two vaccines. So, why shouldn’t the J&J vaccine be a two dose vaccine?
