- Moderna’s medicine is affecting monkeys
- The monkey’s nose and lungs prevent infection
- No results found from the Oxford University vaccine
Work is underway on the worldwide vaccine of Coronavirus. Meanwhile, a study states that the COVID-19 vaccine from the American biotech company Moderna has developed a strong immunity. At the same time, the coronavirus was prevented from spreading infection in the nose and lungs of the monkeys. This has been said in a study in the New England Journal of Medicine. The study says that this vaccine has prevented the coronavirus from spreading infection in the monkey’s nose and this is important because it reduces the risk of spreading the infection to others.
When Oxford University vaccine was tested on monkeys, similar results were not seen. However, this vaccine prevented the virus from going into the lungs of animals and becoming very ill.
Moderna’s study of animals says that three groups of eight monkeys were given two different doses of 10 or 10 micrograms of placebo or vaccine. The monkeys who were vaccinated all produced significant amounts of virus-killing antibodies, which competed with the SARS Cove-2 (SARS-CoV-2) virus.
The point to note here is that the levels of anti-bodies in the monkeys taking both doses were higher than the antibodies of humans who had recovered from the corona. The authors of this study reported that this vaccine also develops various types of immune cells, which are known as T-cells. These cells help to strengthen the immune system of the whole body.
However, it is a matter of concern that these vaccines being developed can reverse the disease rather than increase them.
Four weeks after giving the second injection to the monkeys, they were exposed to the SARS-Cove-2 virus. The virus was transmitted directly to the lungs through a monkey’s nose and a tube. Two days later, there is no re-infection of the virus in the lungs of seven of the eight monkeys. These include both high and low dose monkeys.
On the contrary, the virus was present in the group of monkeys to which the placebo was given. Even after two days of exposure to the virus, monkeys who were kept in the highdose group have no detectable levels of virus in their noses.
