More than 100 million people in India have received the COVID vaccine, which consists of two approved vaccines: Covaxin and Covishield. A third COVID-19 vaccine has been approved for use in India amid the deadly second coronavirus wave. Sputnik V, a Russian vaccine, is considered safe and is similar to the Oxford-AstraZeneca vaccine ‘Covishield,’ which is produced in India.
Sputnik V, which has already arrived in India, provides 92% defence (approximately) against Covid-19. The vaccine’s approval comes as India overtakes Brazil as the world’s worst-affected country by the pandemic. Let’s take a look at which vaccine is best for you as the government begins the third phase of the trial for people aged 18 and up.
Having the COVID-19 vaccine, on the other hand, isn’t enough until the precautions are followed. It’s also a good idea to purchase a COVID-19-specific health insurance package to ensure that you get the best medical care possible.

The Indian government approved Covishield as one of the first two vaccines for emergency use. The medicine is being used in Europe as well. The doses were produced in collaboration with AstraZeneca by the University of Oxford. The Serum Institute of India in Pune produces them. For state governments, the cost of the Covishield has been reduced to Rs 300.
How does Covishield work?
Covishield uses a formula similar to Sputnik V, a weakened variant of adenovirus, a common cold virus found in chimps, ChAD0x1. As a result, it has been altered to resemble SARS CoV-2, but it cannot cause illness. The vaccine causes the human immune system to develop antibodies against the live virus after it is injected.
The vaccine had a 70.4 per cent efficacy rate in phase-3 trials in December 2020. It is based on 11,636 volunteers from the United Kingdom and Brazil who participated in an international clinical trial. It was discovered that when people were given the first dose and then the second dose, the effectiveness increased to 90%.
Any side effects of Covishield?
Pressure, tenderness, warmth, redness, swelling, scratching, or bruising on the injection site are some of the most common side effects seen in one out of every ten individuals. Fatigue, a general feeling of being unwell, chills, a feverish feeling, nausea, headache, joint pain, or muscle ache are all possible symptoms.
Feeling dizzy, stomach pain, reduced appetite, swollen lymph nodes, rash, and excessive sweating are some of the rare side effects seen in less than 1 out of 100 individuals. If you take paracetamol after the vaccine, the chances of developing symptoms are decreased.
The two Covishield vaccine doses are given four to twelve weeks apart and held at a temperature of 2 to 8 degrees Celsius.
In January, Bharat Biotech’s Covaxin received approval for emergency use. In collaboration with the Indian Council of Medical Research (ICMR) and the National Institute of Virology, Bharat Biotech manufactures this coronavirus vaccine in India. Covaxin costs Rs 600 for state government hospitals and Rs 1200 for private hospitals.
How does Covaxin work?
The vaccine was developed by the pharmaceutical industry using a COVID-19 virus sample isolated by the National Institute of Virology. The immune system begins to produce antibodies against SARS-CoV-2, the Covid-19 virus, after vaccination.
According to the manufacturer, introducing immune-potentiators, often known as vaccine adjuvants, boosts the vaccine’s immunogenicity even further.
Based on the Phase 3 trial results, the company performed an interim review and claimed an efficacy rate of 81 per cent for the jab, which is also successful against the UK version.
Are there any side effects of Covaxin?
Pressure, redness, swelling in the upper arm, itching at the injection site, body ache, arm weakness, headache, fever, weakness, malaise, rashes, nausea, and vomiting are some of the more common but uncommon side effects.
Covaxin is also a two-dose vaccine with a 28-day delay between the first and second doses.
Sputnik V Doses and How does it Work?
Sputnik is a two-dose vaccine, with the second dose given 21 days after the first. Two separate vectors are used for both jabs. It makes use of two disarmed adenovirus strains that cause the common cold. They are used to deliver the jab as vectors. The probability of the immune system developing resistance to the initial vector can be reduced by injecting two separate vectors.
Sputnik V employs a cold-type virus that has been designed to be completely harmless. It acts as a carrier for a small fragment of the SARS-CoV2 virus, which is then delivered to the body. It safely exposes the body to a portion of the virus’s genetic code. It recognizes the danger and learns to defend itself without causing illness.
Your immune system develops antibodies against the coronavirus after you’ve been vaccinated.
The vaccine can be kept between 2 and 8 degrees Celsius, making it more convenient to store and transport in India.
Sputnik V ‘s Efficacy
Sputnik V has a 91.6 % efficacy, which is comparable to Moderna and Pfizer. According to clinical trials, Pfizer and Moderna shots have a 95 percent efficacy score, with only Sputnik coming close.
Are there any side effects of Sputnik V?
No one needed to be admitted to the hospital, and any side effects were not linked to the vaccine. Fever is a normal way for the immune system to give the body a boost, and it occurs in some situations. It is quickly treated with paracetamol, and no severe allergies have been identified.
Is Pfizer Effective?
In clinical trials, the Pfizer-BioNTech COVID-19 vaccine showed a 95% efficacy rate against some symptomatic infections. The vaccine was found to be 95 per cent effective in preventing symptomatic COVID infections after two doses. It is effective for people of all ages. It has proven to be highly successful for at least six months, if not longer. However, because of the storage temperature problem, its use in India appears to be limited.
Final Thoughts: What should you choose?
Given that people can book their favorite vaccines right now, obtaining advanced knowledge about the vaccines’ advantages and possible side effects is a wise decision. However, it’s important to note that all vaccines currently in use have been approved and are almost equally successful in preventing coronavirus infections. As a result, people are encouraged to get vaccine shots as soon as they become available.
