Albanian health expert in London shows how the Covid-19 vaccine works

 Meanwhile, the UK has been quick to give the green light to deliver the 40 million doses of the vaccine from Pfizer and BioNTech.

Albanian public health expert Laidon Shapo spoke to A2 from London about these developments, saying that there should be no fear of getting the vaccine, as it has passed all the tests and is safe.

"Every vaccination process has encountered problems, being judged by the population. The effectiveness of the vaccine, its safety, have been handled very carefully by the authorities in the UK. The vaccine was seen in the last stage, with a 95% efficacy in all age groups, this shows that there is no reason for the population to be afraid of the effects. Side effects, of the psychological type, are related to the fact that the vaccine is new. "The only problem is the transportation of the vaccine, which has to stay at very low temperatures."

How does the Pfizer and BioNTech vaccine work?

"Through vaccination, people get a synthetic variant of the virus. This means that a synthetic protein of the viral surface, of the spines, enters the body, where the virus is caught. The cells read this immediately and take it as a foreign body and react to it by creating antibodies and T cells, which go to neutralize this foreign body. It takes 28 days from receiving the first dose of the vaccine to develop immunity. This has been shown by studies of the third phase of the Pfizer and BioNTech vaccine. After the vaccine is made, it takes 12-14 days for the antibodies to start to form, after 21 days the injection of the second dose of the vaccine is required and after 7 days from the second dose, the person is said to have immunity. It is already being discussed how this immunity will be, how long it will last. An answer can now be given only by referring to its "Corona cousins". They have immunity from 6 months to many years. A study has been done and it has been seen that those who passed Sars in 2003, a part of them, 20-30% are ready to fight Covid-19. This makes us somewhat enthusiastic."
