Why 2 COVID Vaccine Doses Are Needed

The emergence of highly infectious variants from the UK, South Africa and Brazil has increased the need to be cautious about the vaccination protocol, as high infection rates will promote continued mutation of the coronavirus , said Monto, professor of epidemiology and global public health. with the University of Michigan School of Public Health.

“If we don’t get viral replication, we don’t get mutations,” Monto said. “So what we need to do is reduce the transmission of viruses and viruses as our main goal.”

Certainly, the vaccine shortage is the biggest problem with the U.S. deployment, Monto said.

“We would have no problem setting priorities if we had all the vaccines we need for everyone,” Monto said. “Most of our problems now are about who needs to get vaccinated, if people skip the line, and none of that would be a problem if we had enough vaccines.

For this reason, the United States must get past it by trying to convince people hesitant about getting the vaccine to get the vaccine, and instead, get two doses of the vaccine to people who really want it, Monto said.

“We have a majority of high risk people who are anxious to get vaccinated,” Monto said. “Given the vaccine shortage, we really don’t have a vaccine on the shelves, waiting to be administered. [those people], then pick up and try to convince those who have not been vaccinated for one reason or another that this vaccine is safe and effective. “

By the time millions of impatient people have been vaccinated, tons of data will be available to provide an unassailable case for the vaccine’s safety and effectiveness, Monto said.

“At the time of vaccine approval, there were concerns that we had data for only two or three months from the deployment of the vaccines,” Monto said. “Now it’s going more and more, and we have millions of people who have received the vaccine.”
