Vaccines have become an integral part of our lives for the last many decades. They have saved numerous human lives across the world. Especially during the present corona pandemic, vaccines have become the only weapon humankind has against the virus. Governments in different countries have been struggling to contain the spread of coronavirus. They are also trying to vaccinate their population as early as possible. Governments have used various ways to restrict the spread of the virus.  Antigen fit to fly tests and quarantines is such checks and restrictions.

What are vaccines?

Scientists use the inactive or weakened portion of a particular organism or an antigen to make vaccines. It helps to activate an immunity system in the body. It helps our body to develop specific antibodies which tackle the pathogens like SARS-CoV-2 viruses. When someone gets COVID-19 vaccination, they are less likely to get infected again with the same virus strain. Although, people with severe health conditions may not be able to get a vaccination in time. It can create many problems in their bodies and even decrease the immunity power inside the body. Vaccines are the only hope to end the different waves of the global pandemic in the present scenario.

COVID-19 is a highly infectious disease and can affect anyone. Vaccine-induced immunity together with in-born immunity creates the most effective way of fighting against COVID-19. Government-approved agencies have conducted multiple tests to approve the vaccines for the public. Thus these vaccines are safe and efficient.

Making of vaccines

It takes a lot of time and effort to produce secure and powerful vaccines for any disease. Fortunately, our researchers can develop different vaccines. These vaccines help to combat the various variants of coronavirus around the world with their continuous work, investment, and communication. According to UNICEF (United Nations Children’s Fund), more than 200 vaccines are developing under different clinical trials around the world. Pfizer/BioNTech Covid-19 mRNA vaccine (BNT162b2) gets approval by WHO for Emergency Use Listing (EUL).

On 16 February 2021, the SII/Covishield and AstraZeneca/AZD1222 vaccines had approval for EUL. Most vaccines need multiple doses the people. These are also given in a certain time interval which allows the body to develop immunity against COVID-19. The UK has made it mandatory for people visiting the nation to have a vaccination certificate. Anyone travelling long distances will require to pass an antigen fit to fly test regardless of the vaccination.

Here are some of the benefits of COVID-19 vaccinations:

Protecting yourself

Vaccines help your body to produce antibodies against COVID-19. If you become infected with COVID-19, these antibodies restrict the potential risk of developing severe or fatal symptoms. Various tests have shown that vaccines prevented a fatality in most cases. Furthermore, a booster dose can protect the person for a longer period of time. A good idea is to take an Antigen test.

Herd immunity

It’s a fact that not everyone can be vaccinated anytime soon. This can happen because of many reasons. The availability of the vaccine is the major cause as of now. However, people can still be safe against COVID-19 thanks to vaccinations among other people in the community. Vaccination gives the hard time to coronavirus because it could significantly lower the infection rate in the community.

So the more people get a vaccination, the less likely it is that other people will have exposure to coronavirus. There will be lesser chances of infection in the future. We know this process as herd immunity. People who can’t be vaccinated are most vulnerable to infectious diseases like COVID-19. To prevent the spread of the virus the UK government has made some strict regulations. It is compulsory for anyone to stay in a 10-day quarantine for anyone looking to be Fit to Fly to the UK. Each such individual also requires a day 2 & 8 PCR test to ensure they do not carry the virus.

Effectiveness of vaccines

Most WHO-approved vaccines pass through various clinical tests in different phases. These tests are mandatory before permitted in the  Emergency Use Listing (EUL). These vaccines will protect 19 out of 20 people from being seriously ill with a different variant of Coronavirus. Some studies indicate that people who take vaccination show fewer symptoms. Even if they come in contact with COVID-19, they recover quicker. Vaccinated people have shown better results. People unvaccinated show severe symptoms for a longer period of time. Antigen fit to fly test will stay in place until the majority of the people do not get the vaccination.


To produce all the Emergency Use Listing (EUL) vaccines the companies follow all safety measures and protocols. These companies develop vaccines by using biotechnology and medical sciences that have been successful for a long time. A lot of testing goes into the process before the vaccine is made available for public use. The data of all the clinical trials and testing have indicated that these vaccines are safe. These are also most effective among the different age groups. Taking Antigen tests helps.


Vaccination develops specific antibodies in the body. These antibodies will boost the immunity power to overcome the infection by COVID-19 in the future. So vaccines maintain our immunity and keep us fit to fight against pathogens. It keeps the human body healthy and protected. A new study suggests that people who took the vaccine might have fewer corona residues in their respiratory organs. Even if they get COVID-19 infection again, they are relatively safe. This makes them least likely to spread the viruses to others. Similarly, mass vaccination programs at the community level will improve herd immunity. It takes us one step closer to getting back to a normal life. So vaccines will eventually help us to get rid of the mask. We can feel fresh oxygen whenever we go out to the market or picnic.

Who will have the priorities for COVID-19 vaccines?

Vaccination should be provided to everyone on a priority basis. However, with limited resources, health care authorities make the short-term goal to protect front-line health workers. These include doctors and nurses, social workers, teachers as well as those of higher importance in the community. Many countries have made it easy for their citizens to book online medicine and test kits.
