According to a statement released by vaccine manufacturer Moderna, the immunity from its covid-19 vaccine should last at least a year. The company said that there is enough evidence to show that the messenger RNA Technology would work even on the new variant of coronavirus that has recently emerged in several countries.
The vaccine developed by Moderna uses synthetic mRNA to mimic the surface of the coronavirus. In this way, it teaches the immune system to recognize the coronavirus and utilize it as soon as it enters the body.
Moderna Says Covid Vaccine Immunity Lasts For At Least A Year
According to the latest reports by the company, it expects to deliver around 1 billion doses of vaccine in 2021. Earlier market estimates had suggested that the vaccine-related sales for the company is likely to be more than $11 billion for the year. The company has already signed several advance purchase agreements with governments across the world.
Interestingly, this is the first time the company has developed a vaccine that was approved by the FDA. Several other vaccine manufacturers who are in the race to develop the covid-19 have rich experience in the industry, and they have worked on several other vaccines in the past. On the other hand, Moderna is a relatively new company in this industry, and it has surprised everyone that they have developed the covid-19 vaccine in such a short duration of time.
The company was the second one in the US to receive emergency use authorization by the FDA. According to the clinical trial data, the vaccine is found to be 95% effective in preventing the disease. The vaccine was tested in people above the age of 18, and the recommendation committee said that the risks were very less and the vaccine could be used for the general public without any problems. The FDA also analyzed that the benefits outweighed the risks in this situation and provided emergency use authorization in December.
The vaccine is to be taken in two doses, and the interval between the two doses is around 28 days. Health experts feel that the interval can vary by some margin without any problems. If there is a delay of a few days in receiving the second dose of the vaccine, it will not cause any problems. As per available data, the first dose of the covid-19 vaccine will deliver around 40% protection. For this reason, it is important to practice all the precautions even after taking the first dose of the vaccine. People who have received the first dose of vaccine should continue to use masks and practice social distancing as much as possible in order to stay away from the infection.
In some cases, it was observed that people got infected with coronavirus even after receiving the vaccine. Health experts believe that this can happen in some cases as the body might not have developed the immunity soon after receiving the vaccine, and there are chances that the infection could get triggered at that point. It is important to stay cautious till the second dose is provided within a month.
According to the data provided by the company, the second dose of vaccine offers about 95% protection from coronavirus. In a recent statement, the company said that the protection is likely to last at least a year. This is promising news as the early estimates said that the protection could last for about six months. This will help the authorities to contain the spread of coronavirus within a short duration of time as a majority of Americans can easily be vaccinated within this year.
The company has so far delivered millions of doses of vaccines to the Federal government. In the near future, the company is likely to deliver more vaccines as they have improved the manufacturing process across the world. The company has also got permission to provide vaccines to various health departments across the world.
