Hello, Friends. When it comes to getting Vaccinated against covid, you might be wondering one thing. Which vaccine is the best? If you get the option, should you choose Covaxin or Covidshield? or should you wait for Russain or the made-in US Pfizer vaccine? Which of these have minimum side effects? I interviewed the famous Virologist, Dr. Gagandeep Kang. And in collaboration with this pharmacy. Their pharmacy covid free India campaign is trying their best to raise awareness about the covid vaccine and things related to them. Also, our government creates a website for online registration for vaccination.
Let's start with the question about the side effects. Which type of side effects are commonly seen? When we get any vaccine, the vaccination area may be painful or get swollen. These are known as the local side effects. And another kind of side effect is systemic side effects. These may include fever, Headache, and many people feel fatigued. In Pfizer and Moderna's mRNA vaccines, these side effects are fewer after the first dose. But in the Astrazeneca vaccine, these side effects are more after the first dose. And few after the second dose.
These are the common side effects, but there are some rare side effects of the vaccines. What percentage of people suffer from these common side effects? approximately 10-35% 0f people.Ans these side effects are commonly seen in every vaccine.
Now, friends. All the vaccines are divided into two categories based on how they work? The first category is the inactivated vaccine-like our covaxin. A virus is produced in a lab and treated with chemicals to inactivated it. It means that isn'tharmful to our body. And then, this virus is used as an inactivated vaccine.
this is how covaxin works. The second category is our viral vector vaccine. Our Covidshiel and Russian Sputnik V both belong to this category. Let take Covidshield as an example to see what is in it. In Covidshield, a Chimpanzee Adenovirus is taken. Adenovirus is a family of viruses. The genetic code in the chimpanzee virus is replaced with the genetic code of the SARAS-COV2 virus.SARAS-COV@ is the virus that causes Covid-19. So a chimpanzee virus that has a genetic code of SARAS-COV2 works like a vaccine in our body. This is known as the viral vector vaccine.
Do you remember the word 'vector' friends? Mosquitoes are often called vectors of dengue and malaria because these mosquitoes carry these diseases to infect us. Similarly, this chimpanzee virus works as a vector. It is getting to our body and infecting us with SRAS-COV2 genetic code so that our body can build up immunity against it.
Now we talk about the advantage of vaccines. First, we look covaxin. It will take 2 doses 4 apart from the week. The vaccine effects will be after 6 weeks. The entire immunization will be complete, and protection will be started. And the interim data, we have seen that there will be 81% protection. And if we look at Covidshield, it gives 71% protection after the first dose. For taking the second dose, it is better to delay it as it has better efficacy. I think it is enough about the vaccines.
