With COVID-19 vaccination goal in doubt, Joe Biden warns of variant’s threat

When Joe Biden set the July 4 goal in early May, he said meeting it would demonstrate that the United States had taken “a serious step toward a return to normal”

With the United States unlikely to reach his self-imposed deadline of having 70% of adults partly vaccinated against the coronavirus by July 4, President Joe Biden on Friday stepped up his drive for Americans to get their shots, warning that those who decline risk becoming infected by a highly contagious and potentially deadly variant.

In an afternoon appearance at the White House, Biden avoided mentioning the 70% target that he set in early May and instead trumpeted a different milestone: 300 million shots in his first 150 days in office. But even as he hailed the vaccination campaign’s success, he sounded a somber note about the worrisome delta variant, which is spreading in states with low vaccination rates.

“The best way to protect yourself against these variants is to get vaccinated,” the president declared.

His remarks came as his administration begins a final push to reach the July 4 goal over the next two weeks. Vice President Kamala Harris and Xavier Becerra, the health and human services secretary, were both on the road Friday, trying to drum up enthusiasm for the vaccine. Harris went to Atlanta, where she noted that less than half of people in Fulton County, where the city is, had at least one shot, and Becerra to Colorado.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
