With a Sniff or a Swallow, New Vaccines Aim to put the Brakes on the Covid-19 Spread

A new light is at the end of the tunnel! It looks like there is hope for the entire world with the latest Covid-19 vaccines being developed. The vaccines are designed to deliver immunity in the easiest ways ever – through a basic sniff or a swallow. According to the latest news, these new vaccines may soon be out and could have a significant impact in reducing the spread of the pandemic.

The primary objective of these new vaccines is to provide immunity to the people without causing any adverse effects. The vaccines come in two different forms- nasal sprays, and oral pills. The nasal sprays aim to deliver the vaccine doses directly into the nasal area to develop an immune response, and the oral pills, on the other hand, aim to induce immunity after being swallowed.

How do the vaccines work?

The vaccines work by using various techniques to stimulate the immune system, which is the body’s natural defence against infections. By introducing COVID-19 antigen in the body, the vaccine helps the immune system create antibodies that can fight off the virus easily.

Benefits of the New Vaccines

  • The new vaccines are portable and easy to administer, eliminating the need for needles or syringes.
  • The vaccines may provide long-lasting protection against COVID-19, ensuring that people are not re-infected.
  • They may be particularly useful in countries with a shortage of medical personnel, as the vaccines do not require trained professionals to administer them.


Although the vaccines are still in the trial phase, the results appear promising. A few companies have started testing their nasal and oral vaccines on humans, and they are getting excellent feedback. It is likely that approval could be granted in the near future, making the vaccine available to the public in no time. With the rising number of COVID-19 cases globally, these vaccines could be instrumental in preventing further spread and reducing fatalities.


The fight against COVID-19 has been the most significant challenge for the world in recent times. Nonetheless, these new vaccines are a beacon of hope in the fight against the pandemic. With the vaccines’ innovative delivery system, they could be a game-changer for the world, providing people with immunity against the virus in the easiest way possible.
