Vaccination 2021. Trends, researches, and why Covid tracing apps have made so much impact.

Vaccination 2021
August 16, 2021

The year 2020 has been a year of the coronavirus, also known as Covid-19. As the world shifts to finding a vaccine for the virus, the governments have looked to integrate their healthcare tools with the new covid tracing apps to help manage the spread of Covid-19.

Governments are in on the new mobile apps designed to help track users infected with the virus. Some of the apps include Belgium’s Coronaleert, the UK’s NHS App, Denmark’s Smittestop, Finland’s Koronavilkku, California’s CA Notify, and many others.

All the apps are designed to use an individual’s phone to exchange codes with other nearby users on the app, like a digital handshake. The code and location of such users are stored in the app. Other users are alerted by the app when a nearby user has been affected by the virus.

Aside from the automated aspects, the app also sends alerts to individuals who have contact with infected people in public places, which will be hard to control using manual tools.

Differences between applications

Most of the apps use a similar database, but there are many functionalities and technical differences between apps. Some apps are designed to use Bluetooth signals, such as the UK, Italy, Finland, etc. Other models, like the Chilean model, are designed to function with GPS technology.

In some countries, like Singapore, a physical token called the TraceTogether Token is shared with all citizens to ensure everyone with or without a smartphone can also get treatment. The content on the mobile phone can only be shared with the authorities if the user approves.

The storage of data using this app differs according to country. For instance, in the UK and Netherlands, the data is stored on the user device, while countries like Italy and Australia store this data on local servers.

In 2020, the Exposure Notification system was designed by Google and Apple. This app was developed using Bluetooth’s system application programming interface (API) to enable digital contact tracing.

However, the app is not a mandatory project. The app is downloaded voluntarily by users. However, in some countries, like Singapore, it is compulsory to have the app depending on your location. Some mandatory people to have the app include migrant workers, businesses, schools, and restaurants.

Generally, the covid tracing app is designed to alter the principles of health programming in many ways. The app comes with autonomy with opt-in/opt-out features, enabling users to consent before sharing the information. Another benefit is its effort to minimize the number of times an individual has to report to the vaccination center for continued examination. The system also reduces the burden of continuous self-reporting, closes the gap in data reporting, and reduces human errors. The system is designed to mitigate the stigmatization of the infected person as there is no need for physical interviews.

The app also helps epidemiologists and behavioral scientists to take preparative steps in case of future pandemics. The system will also help improve the traditional approach to health project implementation.

Your Guide to CDC Masks regulation

In its bid to encourage more trust in the vaccines available, CDC is encouraging people to explore one of the three approved vaccines. According to CDC, the Pfizer-BioNTech vaccine could be taken by people 12 years and older in two different shorts given three weeks apart. Anyone over 18 can take Moderna in two shots given four weeks apart. And finally, Johnson & Johnson’s Janssen can be given to people over 18 in one shot. All vaccines give immunity two weeks after the last shot. Although there are side effects, CDC believes that the benefits outweigh the risk and the risks are all manageable and treatable issues. However, while they encourage this among individuals, they have certain guidelines on mask-wearing for everyone while the pandemic is tamed.

For unvaccinated individuals for two years and above;

  • Face protection is mandatory in public.

  • However, a face mask is not mandated for people in an indoor gathering with social distancing adhered to.

  • Protection should be worn by individuals living in an area with an increasing rate of COVID-19 cases. Especially when in the crowded outdoors or coming in contact with unvaccinated people.

  • Individuals suffering from poor cardio systems may not be completely protected by vaccination. They are encouraged to abide by all rules, such as wearing a facemask unless their doctor recommends otherwise.

If you are vaccinated of all ages;

  • A face mask is required when boarding a plane, bus, or mass transport in and out of the country.

The right way to wear a surgical mask

  • For full prevention, the facemask needs to be put on correctly.

  • Wash your hands thoroughly or apply a sanitizer before wearing your face protection.

  • Do not come in contact with the facemask when putting it on. If you have a problem fitting your mask, get a new one or adjust the existing one.


More solutions are rising to combat the spread and effect of the pandemic. In no time, with the various researches and technology in place, we can hope for a win over the pandemic.
