No vaccines will work until they find one for the common cold and flu. That is the reality and why testing will be so important for years to come.
It is possible we may never even have herd immunity because antibodies are dropping more quickly than expected, similar to the common flu and why we need yearly flu shots.
Common human coronaviruses with no vaccines.
229E (alpha coronavirus)
NL63 (alpha coronavirus)
OC43 (beta coronavirus)
HKU1 (beta coronavirus)
Other human coronaviruses
MERS-CoV (the beta coronavirus that causes Middle East Respiratory Syndrome, or MERS)
SARS-CoV (the beta coronavirus that causes severe acute respiratory syndrome, or SARS)
And the current pandemic
SARS-CoV-2 (the novel coronavirus that causes coronavirus disease 2019, or COVID-19)
People around the world commonly get infected with human coronaviruses 229E, NL63, OC43, and HKU1.
Common human coronaviruses, including types 229E, NL63, OC43, and HKU1, usually cause mild to moderate upper-respiratory tract illnesses, like the common cold. Most people get infected with one or more of these viruses at some point in their lives. This information applies to common human coronaviruses and should not be confused with coronavirus disease 2019 (formerly referred to as 2019 Novel Coronavirus).
Symptoms of common human coronaviruses:
runny nose
sore throat
headache
fever
cough
general feeling of being unwell
Human coronaviruses can sometimes cause lower-respiratory tract illnesses, such as pneumonia or bronchitis. This is more common in people with cardiopulmonary disease, people with weakened immune systems, infants, and older adults.
