Efforts are underway in many places around the world to prepare the coronavirus vaccine. Recently the pharmaceutical company Moderna announced that they had prepared the vaccine, which is effective in killing the virus by 94.5%. At the same time, last week, the drug company Pfizer also informed about the preparation of the vaccine. But amid these claims, medical experts say that 500 things like shark fish liver oil, bark, and sand of a particular tree are to be used in the vaccine, but there is a lack of availability.
According to sources, Professor Robin Shutock, head of the team involved in making the vaccine at Imperial College, London, says, “We don’t know how long the vaccine will keep people safe.” Even if a vaccine comes in the market, it does not mean that it is the best for everyone.

More sharks will be killed for oil
According to Robin, one of the essential ingredients for the vaccine is the oil found in the liver of the shark, which is used in the flu vaccine. Conservation groups believe that shark demand will continue to decrease. They will be killed more.
How to get the bark, when only the Quilaja tree is in the grip of drought these days, the bark of the Quilaja saponaria tree has to be planted in the Novavax vaccine. It has immune system strengthening properties. These trees are currently in the grip of drought and their bark can also be removed only in special months of the year.
Vial crisis for vaccines too
Firefox vials for the vaccine are made of borosilicate glass, their number is also small. Sir John Bell, a member of the Scientific Advisory Group of Emergency, says that there are only 200 million vials that are being used.
