Researchers have shown that they may also come in the form of pills or patches instead of injections
According to CBS News, although the Biden administration has been working hard to maximize the number of Americans vaccinated against Covid-19, government researchers are also working hard to study what form the next-generation vaccine will take.
They can be combined with seasonal flu vaccines, or they can be replaced in the form of pills or small patches instead of injections. Scientists also envision a vaccine that can prevent viruses other than SARS-Cov-2, which can cause Covid-19 and prevent future pandemics.
They are evaluating whether those who are fully vaccinated may need other support doses later this year. In addition to the fact that these can be the same as the first dose, they can also be used as a safeguard against reduced immunity or defense against mutant strains that cause concern.
The three major vaccine manufacturers licensed in the United States, Pfizer, Moderna and Johnson & Johnson, have planned or are testing another vaccine. The booster application is expected to be similar to the current vaccine, but the dose may be smaller.
