Delta Variant Spread Needs a Booster Shot for J&J Vaccine

Due to the increased incidence of the more contagious Delta coronavirus strain, infectious disease experts assess the necessity for booster shots of the Pfizer/BioNTech or Moderna mRNA-based vaccinations for Americans who received Johnson & Johnson’s one-dose vaccine. Some claim to have already done so, despite the lack of public data on whether combining two vaccines is safe and productive, as well as support from US health officials.

People in Canada and certain European countries can already have two different COVID-19 doses. Concerns about how protective the J&J injection is against the Delta version, which was initially discovered in India and is currently circulating widely in many countries, are at the focus of the argument. According to the Centers for Disease Control and Prevention (CDC) Director Rochelle Walensky, Delta, which has also been linked to more severe disease, could become the dominant type of the virus in the United States.

There is no solid evidence that the J&J vaccine is effective against the new strain. According to UK studies, two doses of either the Pfizer/BioNTech or AstraZeneca vaccines are much more protective against the variation than one dose. This week, Andy Slavitt, a former senior pandemic counselor to President Joe Biden, proposed the notion on his podcast.

At least a half-dozen notable infectious disease experts have stated that US regulators must quickly solve the problem. The CDC does not prescribe supplementary shots, and agency officials acknowledged at a public hearing this week that there is no indication of the vaccinations’ effectiveness waning. Stanford professor, Dr. Michael Lin, said, “There’s no doubt that the people who receive the J&J vaccine are less protected against disease than those who get two doses of the other shots.” From the principle of taking easy steps to prevent terrible outcomes, this is a no-brainer.”
