Updates regarding the effective COVID-19 Vaccines

We all are waiting for the day when we can hug our friends, can hang out with our friends, and can get back to normal. This all will be possible only when the vaccine is available, and all the people of the world have been vaccinated against the cruel virus.

 Since the day, the first patient of the virus was reported, the doctors, pharmacists, scientists, and other experts started looking for medicine or injection that can cure the disease. At first, doctors were using flu shots, DPT vaccine, or BCG vaccine to treat the Covid-19 virus. However, these shots were not found effective in the treatment of the disease.

Medical experts continued to work hard to come up with some vaccines to protect the whole human race. Almost all the countries of the world were trying to make a vaccine for coronavirus. Now after one year of the advent of the virus, many countries have narrowed down to the final stages of making a vaccine.

China, U.S., and Russia are on the top of the list of the countries that produced vaccines for Covid-19.  Some of the vaccines that are during the trials were found effective for the treatment of disease include:

  • Pfizer and BioTech Covid Vaccine
  • Sputnik V
  • Oxford AstraZeneca vaccine

Pfizer and BioTech were among the first vaccines developed to cure the diseases. The vaccine underwent three stages of trials on thousands of people. The age group of the volunteers who received the vaccine ranged from age 12 to more than 60 years old. The trials were found to be 90% effective with mild side effects in 50% of cases.

The vaccine includes two doses to be injected at a gap of 21 to 28 days. The countries that are willing to go for this vaccine have to necessarily get two shots. The side effects of the vaccine including pain, cold, fever, and fatigue made the vaccine unsuitable to people with weak immune systems.

The United Kingdom becomes the first country to approve the vaccine safe for human use. U.S, Canada, Britain, and many other countries also gave thumbs up for Pfizer and BioTech covid vaccine,

U.S. drug’s regulatory authorities have approved the vaccine and now the vaccine has made it to the storage rooms of the hospitals in the U.S. The U.S. officials have started to vaccinate the front-line people i.e. the doctors and the people age 80+.

The first person to receive the vaccine was a lady of age ninety years. It is believed that in a few days, the U.S. will vaccinate all the residents. Also, the officials mentioned that everyone will be vaccinated against the virus.

A record card recently went viral all over social media. The record card aims to record the date of the first dose of the vaccine and to indicate the date when the second dose will be due.
