tial data of the early stage trial has been submitted by Pfizer and BioNTech SE already to the US regulator in order to get authorization for the booster dose of COVID-19 vaccine. Information has been given by the drugmakers to the media.
According to Pfizer, BioNTech, third dose has been shown higher rate of neurealizing antibodies in comparison to the couple of doses that has been administered for the SARS-CoV-2. Improvement has been seen in both cases of beta variant and delta variant of coronavirus,
Experts from Pfizer have said, the efficacy from the vaccine may reduce over a period of time. Through a study, it has been observed that the effectiveness may drop to 84% from the peak of 96% in mere four months post the second dose of the vaccine. Some countries like Israel have already approved the booster dose. They have been planning to offer booster dose to its citizens also.
However, health activists are quite disturbed with the idea of booster shot as few rich countries may able to buy them only. Most of the countries in the world have not been able to inoculate its total population yet. Therefore, booster dosages are going to create further disparity among the rich and poor nation. The World Health Organization has already asked for a moratorium on the booster dose till the September end.
During trial by Pfizer and BioNTech, patients have been given booster shot just after eight or nine months from the second dose of vaccine.
In the coming days, drugmaker is going to submit data of the initial trial to the European Medicine Agency along with other drug regulatory authorities also. It is said that data from the late stage trial may be received soon also.
By the US regulators, COVID-19 vaccine third dose has been approved for the people that have compromised immune system from Pfizer and Moderna. Post couple of COVID-19 vaccine doses, relatively weaker protection level is usually seen among these people. Both the vaccines have been administered primarily utilized in USA and some part of Europe.
Booster dose of COVID-19 vaccine is going to beneficial for the people without any doubt. It is definitely going to offer a layer of protection against the COVID-19. Chances of attracting COVID-19 may be lessened in the process. Severity of the disease may reduce significantly as well. So, the booster dosages may be way for forward as far as COVID-19 is concerned.
