Many pharmaceutical companies are already studying this solution, which is in the early experimental stages. For now there is no concrete scientific evidence on the validity of this practical alternative, but within a year, biologists and researchers guarantee, a valid and proven answer could be reached. Pfizer and Moderna began testing it on individuals as early as March and May 2020.
against the coronavirus. This is what would have emerged from a preclinical study. The test is expected to continue in humans by June. However, it still takes a long time before the pill vaccine is validated: a year or more for its use to be authorized. Just think of the clinical trials of the vaccines developed by Moderna and Pfizer, which began respectively in March and May 2020.Nadav Kidron, CEO of Oramed. "The vaccine, the expert explained, could be shipped in a regular refrigerator and stored at room temperature," making it easier to obtain anywhere in the world.'. Not only that: according to the company, the vaccine candidate could offer better protection against coronavirus variants, since it is capable of targeting three structural proteins of the virus and not only the spike, as the other vaccines already administered and formulated act instead.
Need for reliable human clinical data
The studies have been conducted on animals, but the proven validity of the efficacy on humans is lacking, for which it would still take at least twelve months of experimentation. In this regard, the caution on the anti-Covid pill vaccine is maximum. According to the experts it is necessary to have adequate studies to prove the efficacy of oral vaccines. The data on the vaccine, however, have not been published to date. The results of the animal studies appear to be encouraging, but it is not. said that the results on animal models can be translated as satisfactory also for humans.
and in the throat, and oral administration could help stop the disease before it can degenerate into more serious forms.
, is evaluating the possibility of formulating oral intake of the vaccine, via nasal tablets or sprays. Another company, however, ImmunityBio, is conducting phase 1 clinical trials of an oral version of its vaccine. However, the company specifies that this could be used as a second booster dose for the intramuscular vaccine rather than as a single vaccination.
At the moment, however, the vaccine is only available in the classic version with injection. The side effects of vaccination are minimal and do not preclude the possibility of doing sports immediately afterwards.
In the near future, the traditional Covid-19 vaccine will also be available in pharmacies.
