Can I get sick again with the delta variant?

This week’s question seeks to clarify whether the delta variant is more likely to cause re-infection than the other variants, and how severe are the re-infections.

First of all, let’s get out of the subject. Whatever variants are circulating, it is important to get the vaccine even if you have had covid-19 before. We don’t really understand how long protective immunity lasts after contracting covid. It is likely to vary from person to person. Studies have suggested that vaccines significantly activate the immunity of people who have had the virus before and are safer protection against delta and any other variant. While we do not yet know how long the protective immunity of vaccines lasts, it is clear that the immunity lasts at least six months and potentially much longer. Let us now turn to the question in question. We asked Andrew Noymer, professor of public health at the University of California, Irvine, for advice.

Researchers are studying the likelihood of people contracting COVID-19 a second time. Today, we know that re-infection can occur, as can infections in fully vaccinated people.

More research is needed on the delta, but a new study has suggested that the variant may escape natural antibodies produced in our bodies after infection.. After analyzing blood taken from 162 patients, the scientists found that while the antibodies from people infected with Sars-CoV-2 did not neutralize the delta variant very well, after a single dose of the vaccine, the antibodies from those infected Previously, they were able to neutralize the four strains of the virus tested.

Delta: what do we know about the new variant that alerts the world

Antibodies from people who only received one dose of the vaccine and who had not had the virus before did not fare as well. Antibodies from people who have been fully vaccinated but had not performed well, confirming further evidence that the vaccines are extremely effective against the delta variant. Previous evidence suggests that if you are not vaccinated, whether or not you have had covid, you are more vulnerable to the delta variant.. We repeat, the vaccine is to defeat the virus. Noymer says the real problem with the delta is not that it makes people sick, but that it spreads very quickly, creating more possibilities for infection and forming new variants that can better evade vaccines. “I’m concerned about the delta, but not just the delta,” says Noymer. Other variations, he says, “wait behind the scenes.” There are more than enough unvaccinated people in the United States to trigger a new wave of covid, according to Noymer. “There may be a variant around the corner that the vaccines don’t work for.”he commented.
