Pills and sprays “under development” … a new generation of corona vaccines “better than injections”

US drug companies and government laboratories are working to develop vaccines against the emerging corona virus that are taken in the form of pills or nasal sprays, and they are easier to store than current vaccines that are taken by injection, according to a report by the Wall Street Journal.

Developing companies say that these vaccines will have the ability to provide immune responses that last for a longer period of time and will be more effective against the mutated strains, which may help avert future epidemics.

The vaccines currently authorized for use in the United States, such as “Pfizer” and “Moderna”, require very low temperatures to store and transport them. The person who receives the vaccine takes two doses at intervals.

The new vaccines will bypass these restrictions, and governments can reach rural areas more easily. The report says that most of the vaccines currently being tried around the world are taken by injection, but there are two vaccines being developed for oral administration and seven other formulations of nasal sprays.
