When we get sick, our body does not wait for the pathogens to invade our tissues and systems. Instead our body fights with its immune system. When germs such as COVID-19 invade our body, our immune system attacks and multiplies. When a germ such as COVID-19 enters our body, our immune system may need several days or weeks to be sufficiently fighting against it. Even though we have learned with other germs that the immune system usually produces memory T cells which help develop immunity faster, the mechanism after a COVID-19 illness is still not clear. To help you gain better insight about acquired immunity, here is a video that compares COVID-19’s immunity with six other diseases:

Immune system may need help from us, such as vaccination. And as far as the vaccination goes, we are familiar with plasmid DNA and currently with mRNA vaccines. Even though both of them have been proposed as a new method to develop vaccines, plasmid DNA vaccines have been researched more likely due to concerns of the instability of mRNAs. Here is a table of 3 vaccine types with their development stages compared with a line graph by Genetic Engineering & Biotechnology News:

Pre-clinical efficacy of mRNA has been better understood as COVID-19 vaccine researches have continued. mRNA may be even more complex than plasmid DNA because of the modifications plus the formulations needed for stability and delivery. Even though mRNA sounds like a new discovery, it has been researched just like plasmid DNA vaccines and even though we have a long way to understand both these methods more comprehensively, new COVID-19 vaccines are the silver lining. As we keep you updated about the progress of vaccine technology, you can make sure you get proper assistance for your upper respiratory tract discomfort by the comfort of your home, via FluAI.
