Vaccine hopefuls are looking at early 2021. 

Scientists and medical experts across the world began testing vaccines when COVID-19 became an issue. Vaccines, for those of you who missed it in high school chemistry, are designed to activate our body's immune system to fight off infection without making us sick. This is largely trial and error, finding the right formula that safely fights off SARS-COV-2 (the technical strand of the virus that causes COVID-19) or any kind of infection, takes time.

The COVID-19 trials have made headway, with more progress made this last week, giving hopefuls like Dr. Anthony Fauci another reason to guess that a vaccine will be available by early 2021, if not the end of 2020.

An antibiotic is used to treat bacterial infections, but COVID-19 is a viral infection. 

Some may wonder why the entire medical community is focused on a vaccine instead of a treatment plan. The fact of the matter is that a vaccine would have the ability to stop the virus before it landed you in a doctor's office complaining about your lack of smell. An antibiotic sounds like a great idea, until you realize that antibiotics are designed to fight bacterial infections, which COVID-19 is not (it is a viral infection). You've probably heard of physicians treating COVID-19 patients with antibiotics, but that's largely due to the unknown nature of the disease and the fact that many early patients showed signs of bacterial pneumonia (and were treated as such).

Like most viral infections, you treat COVID-19 by working to ease the symptoms you have. Wash your hands, disinfect surfaces in your home, increase your fluid intake, get plenty of sleep, boost your immune system no matter how healthy you are, and follow other directions by your primary care doctor.

Herd immunity is worth defining. 

Going to a "coronavirus party" to get the disease and hope your body builds antibodies? Not a good idea. When discussing herd immunity, experts are not looking at extreme scenarios of everyone purposefully sharing infection. On the contrary, herd immunity is a generally slow process, built up over time as more individuals get sick and recover from a virus, fighting off the pathogen in question. Normally, herd immunity is considered to be "achieved" if a high percentage (think 80-90 percent) of the population is immune to infection. This is often discussed in correlation with a successful vaccine, like the eradication of smallpox from the United States in 1972. Herd immunity could hypothetically happen naturally, but this would require leaps in infection that could be detrimental depending on the severity of those infected (and the ICU beds this would take up).

If enough individuals are infected, fight off the pathogen, and build up immunity for that pathogen, a disease can die out. This is a risk — it takes time, it's hard to track, and individuals who are immunocompromised are still the most at-risk group of the population.
