- To make the vaccination process simpler and faster, researchers are working to develop the next generation of COVID-19 vaccines, namely in pill and nasal spray forms.
- Historically other vaccines, such as those for polio, started as injections but oral vaccines were developed.
- More research is needed to find out if these oral or nasal spray vaccines will be as effective as injectable vaccines.
The three COVID-19 vaccines authorized in the United States may be key to helping get the pandemic under control in the near future.
But while these vaccines, released by Pfizer-BioNTech, Johnson & Johnson, and Moderna, are effective, they do come with some challenges.
All require getting an injection, which can make people with needle phobias extremely hesitant to get the shot. Additionally, side effects including feelings of fever, flu-like symptoms, and arm soreness are common with all three vaccines.
The Johnson & Johnson vaccine has been paused as officials investigate extremely rare blood clots that may be associated with the vaccine.
