Throughout every country, the dangers of the worldwide pandemic, coronavirus, still linger. Although some populations have begun to get back to the way it used to be slowly, many are still worried about the likely second wave of coronavirus, also known as COVID-19. Looking at countries in the Southern Hemisphere that up until late June appeared to have had COVID-19 well under control (like Australia), there has been a large surge in cases in July as the typical winter respiratory infection season arrives. In January 2021, when many are fed-up with social distancing, there may well be a huge rise in cases in the Northern Hemisphere respiratory infection season. Many are hoping for a vaccine to help stop the spread of the dangerous virus. However, there are difficulties with getting a COVID-19 vax.
Developing a brand new vaccine is a significant medical and scientific discovery. It can take decades to finally find a successful vax, even with the urgency of the situation. Remember drug companies are motivated by profits – if a drug is likely to be profitable, they’ll pour more money into trying to develop it. Coronaviruses are one of the main causes of the common cold (as well as rhinoviruses, RSV and parainfluenza). Almost all of us get at least one cold every winter. So there would be a huge incentive to developing a successful vaccine to a disease we all get every year. There has never been a successful vaccine to a coronavirus. Why will it be different with COVID-19? Hopefully, it will be different, but we have to be realists.
Also, studies have shown that those people who acquire COVID-19 have a rapid drop off in their natural immunity – 23-fold in only a few months! The immune system generally builds a more robust response to “naturally” acquired infections, than to vaccines. So if a vaccine is developed, people may need to be re-vaccinated at least every 3 months.
Once the corona vax is created, many people may be fearful about getting vaccinated. Even with the vaccine tested and numerous trials are done, it’s difficult for people to trust a new vaccine entirely. These are reasonable concerns. It is wise not to be an ‘early adopter’ of new medications, often side-effects become more well known once the medication has been in broad community use after the initial trial phases.
Facing the Reality of a Vaccine
While a COVID-19 vax could help billions of people around the world, it’s essential to be realistic. Probably within the first few weeks of distributing a vaccine, there will be countless stories about side effects, medical syndromes, and scary reactions. Even for someone who is pro-vaccine, this could be scary to hear. It’s important to be realistic that many people are going to be scared to take the vaccine, not based on science, but on the horror stories spread around. Many people are probably going to want to wait before getting vaccinated, which is entirely understandable.
This means if a vax if found and ready to be given to the public, it won’t stop the pandemic in its tracks. It will definitely take time.
