The new form of the enhanced Corona vaccine may be a "patch" or a "pill"

The American "cbsnews" network reported that scientists are working on a new form of the enhanced Corona vaccine to be in the form of a "patch" or "pill" instead of injections or it may be combined with the seasonal influenza vaccine.

Scientists also envision the shape of second-generation vaccines that may protect against viruses bypassing the Corona virus, and could avoid future epidemics, and scientists also evaluate whether those who have been fully vaccinated may need booster injections later this year.

The additional doses may be nearly identical to the first doses, which are given as a guarantee against the possibility of diminished immunity or modification of defense against the mutant strains of concern.

Here's what we know about the landscape of the next generation of coronavirus vaccines

Booster doses of the Corona vaccine

The three major vaccine manufacturers that have authorized doses in the United States - Pfizer, Moderna and Johnson & Johnson - have plans or are already testing an additional dose and it is expected that booster shots will be very similar to the current vaccines but can come in a smaller dose.

Dr. David Kessler, chief scientific officer for the US administration's response to Corona, said, "With so many vaccines, we understand that at a certain time we need a boost, be it 9 months or 12 months, and we are preparing for that, and the boosters can also be mixed with the annual seasonal flu vaccine ".

Moderna said it plans to conduct early trials of these types of combined shots this year, as other formulations of vaccines are already being used frequently to immunize young children against multiple diseases with one doctor's visit.

However, administration officials said that no decision has yet been reached on how to use the booster doses or whether they are needed.

What about the new variants of the Corona virus?

While the booster doses work to replenish the body's immunity against the virus by mimicking parts of the original strain that were first identified in China, vaccine makers are also trying to adjust their doses to address newer variants of the Coronavirus, some of which are spreading more quickly and may cause more serious disease.

Seasonal influenza vaccines are changed regularly to address the mutations that have been detected in the virus around the world, and Dr. John Mascula, head of the Vaccine Research Center at the National Institute of Allergy and Infectious Diseases, said that understanding Corona mutations is a "major focus" of scientists.
