In Britain, Pfizer’s Corona virus vaccine has been allowed to be used in emergency. Pfizer’s Corona virus vaccine was found to be 95% effective in the last-stage trial.
Britain is the first Western country to have licensed a vaccine for Kovid-19. Along with this, Pfizer / BioNTech vaccine will be given to those who are at high risk of infection. The vaccine has been approved by the Medicines and Healthcare Products Regulatory Authority (MHRA). MHRA was given the authority to approve the vaccine before January 1 under special rules.
40 million doses of Pfizer vaccines purchased by Britain were found to be 95% effective in the last trial. The company has stated that the first doses of the vaccine will be delivered in the coming days. The UK has purchased 40 million doses. Company Chairman Albert Borla has said, “Wearing permission for emergency use in Britain today is a historic opportunity in the fight against Kovid.” mRNA-based vaccine Moderna’s vaccine is also based on the same mRNA technique as the Pfizer vaccine. The company has claimed that its vaccine has been found to be 94.5% effective in early last stage data. Moderna’s vaccine produced antibodies in the young as well as older people, which acted against the virus. Temperature is a big challenge
American company Pfizer has developed the Corona vaccine in collaboration with Bioentech in Germany. It was up to 95% effective in Phase 3 trials. This is by far the most effective vaccine based on trial results. However, Pfizer’s vaccine has to store at temperatures below zero (-70 ° C), which is its biggest drawback. The price of the vaccine will also be good. The company has signed a deal with the US government for $ 19.50, so the price of the vaccine in the open market can be up to double. American pharma company Moderna Inc has reported that governments will have to pay 25 (1,854) to $ 37 (2,744) a dose for their corona virus vaccine. The Covishield government being formed in India will get a lower price (3 to 4 dollars i.e. 225-300 rupees) because it will buy a lot of doses. But the general public will have to pay 500 to 600 rupees for the vaccine.
Earlier, Professor Andrew Pollard of Oxford University and AstraZeneca’s Vaccine Trial claimed that it would be 10 times cheaper than Pfizer. Actually, the Pfizer vaccine has to be kept at a temperature of -70 ° C and two injections will be made at a difference of few weeks. The Oxford vaccine has to be kept at fridge temperature.
