Endemic common human coronaviruses
About 20% of colds
Types 229E, NL63, OC43, and HKU1
usually cause mild to moderate upper-respiratory tract illnesses,
like the common cold.
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,
weakened immune systems, infants, and older adults.
Cross-reactive memory T cells associate with protection against SARS-CoV-2 infection in COVID-19 contacts
Cross-reactive immune responses
Common cold coronaviruses and SARS-CoV-2
The frequency of baseline cross-reactive T cells,
is correlated with the infection outcome following SARS-CoV-2 exposure,
and we observe significantly higher frequencies of cross-reactive memory T cell responses in PCR-negative contacts.
Here we assess 52 COVID-19 household contacts
Studied peripheral blood mononuclear cells
(Lymphocytes as opposed to neutrophils)
T cells specific for spike, nucleocapsid, membrane, envelope and ORF1 SARS-CoV-2 epitopes,
(Open Reading Frame, about a tenth of the viral genome)
These T cells cross-react with human endemic coronaviruses.
We observe higher frequencies of cross-reactivity
Memory T cells cross reacted with nucleocapsid-specific antigens significantly
Memory T cells did not seem to cross react with pre-existing spike-cross-reactive T cells
Our results are thus consistent with pre-existing non-spike cross-reactive memory T cells protecting SARS-CoV-2-naïve contacts from infection,
thereby supporting the inclusion of non-spike antigens in second-generation vaccines.
66% per cent of over-80s are double vaccinated
68% per cent of over-60s have been boosted
1.3 to 2.1 million lives at risk

Of the 39,791 cases
3,709 were symptomatic
36,082 were asymptomatic
