Covaxin or Covishield Which is Better ?
If we start by talking about the Covid-19 vaccination drive in India, it began on 16th January 2021. The vaccination program in India began in phases. The government decided to vaccinate people depending on the requirements. For Phase I, the government notified that the front line workers like the policemen, doctors, cleanliness workers, nurses, etc. should get the vaccine. In March 2021, the government started the vaccination program for people between the age group 45 to 60 years, and with comorbidity. Then, in May 2021, the third phase began for the people of the age group 18 to 44 years. Now, the work on bringing vaccines for children is going on. In every state, both vaccines have been provided. However, the public has been reluctant to know Covaxin or Covishield Which is Better Vaccine ? out of the two available ones.
Covaxin or Covishield Vaccine Dose, Efficacy
To start with we would like to talk about the developers of the two vaccines. Hyderabad-based Bharat Biotech International Ltd. has developed Covaxin along with the National Institute of Virology (NIV) and the Indian Council of Medical Research (ICMR). However, Oxford-AstraZeneca has developed Covishield with Serum Institute of India (SII).
Now, to understand the functioning of the two vaccines, you must know the type of vaccines. Covaxin is a viral vaccine (inactivated). The technology used to develop this is Whole-Virion Inactivated Vero Cell. These contain inactivated viruses that don’t affect a person. However, they teach a person’s immune system and prepare it for defense against the virus. Previously, health authorities have used this technology to produce vaccines for various diseases. These are seasonal influenza, polio, rabies, Japanese encephalitis, and Pertussis.
On the other hand, the authorities have developed Covishield using a different technology. ChAdOx1 (Chimpanzee adenovirus) is used as a modification for carrying Covid-19 spike protein in human cells. Again, the virus doesn’t infect the human cells but teaches them about the defense mechanism and prepares accordingly. Before Covid-19, the officials have used this technology to prepare the Ebola vaccine.
This means that even though the functioning is different, both the vaccines help the receiver in a similar way.
Covaxin or Covishield? Vaccine Efficacy
Now that you have read the functioning of the vaccines, we would like to talk about efficacy and doses. Before that, it’s important to understand the meaning of efficacy. Many people confuse efficacy with efficiency. Efficacy is the measure of prevention of disease by the vaccine. Also, efficacy talks about the prevention of transmission under controlled circumstances. Here, the comparison is between a vaccinated group and a placebo group. On the other hand, the effectiveness of a vaccine talks about the performance of a vaccine. However, there is a relation between these two terms.
A vaccine with higher efficacy like Moderna’s vaccine (94.5%) and Pfizer’s vaccine (90%) are considered more effective than the others. Now, to explain this properly, we would like to give an example. If a vaccine has 90% efficacy during the trial, it means that there was a 90% case reduction in the vaccinated group, in comparison to the placebo group.
Now, mentioning the efficacy rates of Covaxin or Covishield Which is Better ? , both of these have shown satisfactory results since the beginning. However, the effectiveness of Covishield is 90% and that of Covaxin is 81%. Therefore, there is not much difference in both vaccines.
Along with the information provided so far, we would like to mention the doses. Talking about Covishield, there should be a gap of at least eight weeks between the two doses. Earlier, this gap was four weeks. On the other hand, the gap between two doses of Covaxin should be from four to six weeks. However, now the government has also notified that the more the time between the two doses, the more effective the vaccines become.
Covaxin or Covishield? Which has what side effects?
As mentioned above, WHO has notified that it’s normal to have certain symptoms or side effects after getting the vaccine. Thus, everyone can face various symptoms based on their immunity and the vaccine they have received. To understand this Covaxin or Covishield Which is Better Vaccine ?, you can read the information on the vaccines here.
One can face pain at the injection site after receiving Covaxin. Also, the person can face fatigue and dizziness along with rashes in the body. Furthermore, the receiver may have swelling in the throat or breathing difficulties. Other reactions include vomits, allergies, nausea, body aches, fever, etc. Also, the person can have stiffness in the upper arm.
Now, talking about the effects of Covidshield, the person can have headaches and pain at the site. Also, the person can face itchiness at the site along with tenderness, warmth, and swelling. So far, neither of the vaccines has shown severe effects.
