What is vaccine?
- Vaccines prepare your body to fight a disease, virus, or infection.
- Vaccines contain weakened or inactivated parts of an organism that cause disease.
- These prompt the body’s ‘immune system’ i.e. the immune system to recognize the infection (invading virus) and make antibodies in the body against them which help our body to fight the external attack.
Are vaccines Safe?
An early form of vaccine was discovered by Chinese scientists in the 10th century.
But in 1796, Edward Jenner discovered that a single dose of mild smallpox infection protected against severe smallpox infection.
He did further study on this. He also tested his theory and his findings were published two years later.
That’s when the word ‘vaccine’ originated. The vaccine is derived from the Latin word ‘vacca’ which means cow.
The vaccine is considered one of the greatest medical achievements of the modern world. According to the World Health Organization, about two to three million lives are saved every year because of the vaccine.
The CDC says that the vaccine is thoroughly tested before it is brought to market. They are tested first in laboratories and then on animals. Only after that the vaccine trial is done on humans.
In most countries, people are vaccinated only after getting permission from local drug regulators.
Vaccination does have some risks, but like all medicines, it is nothing compared to its benefits.
For example, some childhood diseases that were very common until a generation ago have rapidly disappeared due to vaccines.
Smallpox, which killed millions of people, is now completely eradicated.
But it often takes decades to achieve success. Nearly 30 years after the launch of the global vaccination campaign, Africa was declared the only polio-free country. This is a very long time.
Experts have warned that it may take months or possibly years to get enough vaccinations against Kovid-19 around the world, only after which we will be able to return to normalcy.
how are vaccines made?
When a new pathogen such as a bacterium, virus, parasite or fungus enters the body, a subset of the body called antigens begin to produce antibodies to fight it.
A vaccine contains a weakened or inactivated part of an organism that causes disease.
These trigger the body’s ‘immune system’ i.e. immune system to recognize the infection (invading virus) and make antibodies against them in the body which help our body to fight off the external attack.
Conventional vaccines develop the body’s ability to fight off an external attack.
But now new methods are also being adopted to develop the vaccine. These new methods have also been tried in making some corona vaccines.
Are there other vaccines for covid?
Chinese pharmaceutical company Sinovac has made a vaccine named ‘Corona-Vac’. The company has used the traditional method to make this vaccine. According to the company, inactive parts of the virus were used to make this vaccine. However, many questions are being raised about how effective it is.
Many vaccines are being given in India. Covishield which was developed by scientists from AstraZeneca and Oxford University and manufactured by Serum Institute of India. And the second vaccine is Covaccine made by the Indian company Bharat Biotech.
Russia has developed its own corona vaccine named ‘Sputnik-V’ and it has been prepared by making minor changes to the version of the virus. This vaccine is being used in India. Moderna Vaccine has also been approved for use in India.
Should I get the covid vaccine?
It has not been made mandatory to have a Kovid vaccine anywhere. But most people are advised to get vaccinated. However, there is an exception here in the case of people suffering from health issues.
The CDC says that the vaccine not only protects against Kovid-19, but also protects others. In addition, the CDC also describes vaccination as the most important way out of the epidemic.
The World Health Organization estimates that to prevent infection, at least 65-70 percent of people will have to be vaccinated, that is, more and more people will have to be vaccinated.
It is true that it takes many years for scientists to develop a vaccine, but the pace of finding a solution to the corona epidemic has accelerated. That’s why the World Health Organization is working closely with scientists, business and health organizations.
In short, immunizing billions of people will prevent the spread of COVID-19 and move the world towards herd immunity. Experts say that only through herd immunity will the world be able to return to normal life.
Will the vaccine affect the Delta and Delta Plus variants?
Health experts recommend taking the vaccine to avoid the corona virus. He says that whatever vaccine is available, it should be installed. Many are concerned about the vaccine’s effect on the Delta and Delta Plus variants.
However, according to a study published in the New England Journal of Medicine, two doses of Pfizer or AstraZeneca are just as effective against the infectious delta variant as against the previous alpha version. Officials have said that the vaccine is very effective against the delta variant, which has become a headache worldwide. However, the study reiterates that a single dose of the vaccine is not sufficient for greater protection.
According to this study, two doses of Pfizer are 88% effective against the delta variant and two doses of AstraZeneca are 67% effective against the delta.
Kovid Vaccine: Will the Delta Plus variant be affected?
Covid: What is Delta Variant?
On the other hand, the Delta Plus version is only associated with the Delta version. Most people are worried about this new form of corona. Some believe that the new ‘Delta Plus’ variant may also overshadow the corona vaccine.
However, VK Paul, member of NITI Aayog, said some time ago, “The Delta Plus variant of the corona virus is yet to be studied and no scientific data exists yet, which proves that the new version enhances the effectiveness of the virus.” Can reduce. Vaccine.” turn it down.”
It is clear that at present, nothing has been said by the government about the effect of Delta Place on the vaccine and research is still going on on this. However, general guidelines recommend taking both doses of the vaccine.
Why am I getting covid even after taking the vaccine?
- No vaccine is 100% effective. Even after getting the vaccine, scientists call this infection ‘break through infection’. In most cases of rupture from infection, symptoms are mild.
- According to experts, the chances of getting Kovid after getting the vaccine are very less and it is not that serious either.
- But people are worried about the sudden increase in cases of Kovid-19 amid the global vaccination campaign.
However, the cases of infection are very less and according to experts, their number is as much as it was feared earlier.
- Phase III trials of major COVID-19 vaccines showed more than 90 percent efficacy against the infection. But studies in Britain, Israel and Kadana suggest the vaccine’s effectiveness is being seen slightly lower in the outside world, believed to be due to the delta variant. It is estimated that personalized vaccines provide 60–90 percent protection against symptomatic infections.
- According to Public Health England, of the 105,598 delta variants reported in England in the four weeks leading up to 19 July, about 17 percent were people who had completed their vaccinations. Public Health England considers people fully vaccinated to be those who have completed 14 days after taking the second dose.
- 60 percent of people in Israel have been vaccinated. There, out of 6,000 people found infected in the week of July 21, 52 percent were such that their vaccination was completed.
- However, among those who are getting infected after the completion of vaccination, the condition of very few people has become serious.
- According to a study by Public Health England, those receiving the Biotech/Pfizer vaccine are still 96% less likely to be hospitalized. At the same time, Oxford / AstraZeneca’s vaccine is 92% effective in this case.
Delta version: Eight-week gap best for Pfizer-Biotech vaccine
- A longer interval between the first and second doses of the Pfizer-Biontech vaccine allows the body’s immune system to produce more antibodies that fight the infection. UK researchers have found this in a study.
- Experts say that this discovery has strengthened the decision of the UK government, under which the interval of the initial three weeks was extended.
An eight-week hiatus is considered very appropriate in dealing with the delta variant.
- In the UK, the interval between two doses was increased to 12 weeks at the end of 2020.
- But then the vaccination campaign covers people of all ages and everyone over the age of 18 has received at least the first dose of the vaccine, so people are being asked to move on to their second dose. . He is being told that he should get a second dose after eight weeks.
- The government funded this study. The study appeared in a pre-print paper, although it is yet to be reviewed by experts.
