What is in COVID-19 vaccines? Is it safe? Who will decide?

In addition to this vaccine, vaccines against the coronavirus are being developed in various countries worldwide, and soon several effective vaccines will be available in the world to control this epidemic.
Officials in Pakistan say the corona vaccine could be available in the first quarter of 2021. Pakistan's federal cabinet has also approved the provision of 15 150 million for the purchase of vaccines. Dr. Faisal Sultan, Special Assistant to the Prime Minister for Health, said that the vaccine would be given first to frontline workers in the country. While many people are desperate to get these vaccines as soon as possible, some seem anxious to inject an unknown drug into their bodies.

How do we know if the vaccine is safe?

This is the first and most basic question scientists ask before any vaccine is developed and tested or a new treatment is introduced. According to BBC News Health Director Michelle Roberts, experiments on the safety of any vaccine begin at the laboratory level and are performed on animals or human cells. It is then applied to the human body.

What is the role of experiments in vaccine development?

Humans need a large number of volunteers to experiment. The Pfizer / BioNTech vaccine has been tested on about 400,000 volunteers. Unless the laboratory experiments prove that the results are positive and encouraging and that scientists do not identify and believe that the vaccine or treatment developed is effective, it Is not sent to the next step. N
In this process, half of the volunteers are vaccinated with the prepared vaccine, while the rest are given a simple solution. In this process, researchers and volunteers involved in the experiment are not told who has received the original vaccine and the simple solution unless their laboratory results have been analyzed. This is done so that there is no bias in the process.

 Corona vaccine experiments have been done very quickly, but no steps have been taken in the process. Vaccine trials at Oxford University and the pharmaceutical company AstraZeneca were stopped at one point voluntarily to find out why one in thousands of people involved in the experiment died. The vaccine trial was resumed only after it became clear that the person had not died of a vaccine-related cause. The results of all these experiments are independently tested and evaluated.

Who approves new vaccines or treatments?

The use of any new vaccine on humans can only be authorized by an institution set up for this purpose in any country. In the UK, this is the job of the MHRA (Medicine and Healthcare Products Regulatory Agency) which only allows use if it is satisfied that its human use is safe and effective. "People need to be convinced that the standards we work on are world-class," said Dr. John Ren, head of the first company to approve the corona vaccine for general use worldwide. The vaccine continues to be tested after approval to ensure that it has no harmful health effects or long-term effects. Anyone suspected of having or suffering from the harmful health effects of this vaccine can complain to the Drug Regulatory Agency.

What's in Corona Vaccines?

Many corona vaccines are currently being developed worldwide, some of which use a weaker version of the virus. The vaccine, developed by Oxford University and AstraZeneca, uses a harmless virus that resembles the SARS code 2, the corona virus. Vaccines developed by Pfizer, BioNTech, and Modern have used a genetic code that causes the human immune system to respond and are called mRNA vaccines. These vaccines do not modify human cells but only increase the body's resistance to the corona virus. A few vaccines have been used to obtain proteins from the corona virus. Other ingredients, such as aluminum, are used in vaccines to make them more stable and effective. R can be made.

Will, the vaccine make me sick?

There is no evidence that any of the ingredients in the vaccine could be harmful if ingested in such small quantities. Vaccines do not make you sick, but they teach your body's immune system how to fight off a specific virus if it enters the body. Vaccines do not make you sick. On the contrary, it teaches your body's immune system how to recognize and fight infections.
Some people do show minor symptoms after being vaccinated, such as muscle aches, mild fever, and so on. It is not a disease but a reaction of the body to a vaccine. It is rare to see an allergic reaction to a vaccine. Any approved vaccine contains its ingredients. We also warn you that the process of spreading anti-vaccine false stories through social media has begun and is not based on science at all.

Is it safe to vaccinate a person infected with code 19?

If a corona virus vaccine is approved, it will likely be given to people who have had code 19 in the past. This is because natural immunity cannot protect forever, and we have seen cases of second-time coronavirus infection.

Are animals safe in the preparation of these vaccines?
Some vaccines, such as the shingles vaccine or the pediatric flu vaccine, use pork gelatin. Similarly, some vaccines are made from chicken eggs or chicken cells. Hundreds of vaccines are currently being worked on. We do not currently describe all the ingredients used in them, but most cod vaccines will not harm animals.

I don't need to worry?

In this regard, we have significant scientific evidence which shows that infections can be prevented only through vaccines. According to the results so far, corona virus vaccines effectively prevent people from becoming very ill and saving their lives. The first dose of the coronavirus vaccine will be given to those who need it most, such as the elderly who may become seriously ill. It is unknown at this time what he will do after leaving the post. If they are effective in this case, the majority of the vaccine will eradicate the disease.
