Anthony Fauci, President Joe Biden's chief medical advisor, now suggests that Americans vaccinated with covid-19 may need a booster shot. This news comes at a time when the number of covid-19-related cases in the country continues to increase, thanks to stagnant vaccination rates and the rise of the ultra-transmissible Delta version.AdvertisementCNN's State of the Union featured a statement from the nation's leading infectious disease expert, saying that certain Americans might get a third jab.People with suppressed immune systems, transplant patients, cancer chemotherapy, and auto-immune disease are all examples of people that could be affected by a third booster.This is a departure from Fauci's earlier comments that booster shots were not necessary to augment previous doses of vaccine. He stated that the Center for Disease Control and Preventions Advisory Committee on Immunizing Practices was reviewing data and could recommend a third shot, especially if preliminary studies indicate that there may be a decline in immunity among vaccinated people. He cautioned, however, that the situation is still in flux.He said that the CDC's position on whether a vaccine booster shot was necessary is still a work-in-progress. It is like many other aspects of the pandemic.The New York Times reports that early data from an Israeli health ministry study showed that Pfizers covid-19 vaccine only 39% of the time was effective in preventing infection in the country. This is down from 95% in January and April. It should be noted, however that the vaccine was still more than 90% effective in preventing severe illness from this virus.A second UK study found that the Pfizer vaccine was 88% efficient against the prevention of symptoms from the Delta strand. This is comparable to its effectiveness against Alpha.AdvertisementFauci stated that a booster shot might increase effectiveness rates. However, the ACIP will continue to examine the data.Worldwide, health officials have increased their concern about the Delta variant of the coronavirus. It is more transmissible that past strains. According to the CDC, the strain now accounts for about 80% of all cases in the United States, up from 30% in June.AdvertisementThe spread of the disease coincides with an increase in global total cases. According to the World Health Organization, the number of cases per day increased by approximately 12% over the past week. It rose from 400,000 to 490,000. Fauci stated Sunday that the U.S. has seen the highest spikes in cases in states where only half of the eligible population is vaccinated.It's almost like there are two types of America. Fauci explained to CNN that we have two parts: the vulnerable, unvaccinated, and the more protected, vaccinated.AdvertisementNow, I am one of the vulnerable groups Fauci described. Since I was a teenager, my immune system has been protected by a wonderful genetic condition. I'm more than happy to be stabbed once again, if it keeps the Rona away. I suggest you give me as many boosters possible. Heck, I want covid-19 in my life to have a vaccine.
