Pandemic changing age profiles

Burden and characteristics of COVID-19 in the United States during 2020

Columbia University and NIH, Director Francis S. Collins, Nature


United States, 2020, highest numbers of reported cases and deaths

In the light of later antibody studies

March 11.3%

December, 24.5%

Population susceptibility at year’s end was 69.0%

So, 31% of population had been exposed

(100 million people)

Prevalence rates rose above 0.8% by end of 2020

As high as 2.4% in some major metropolitan areas

Infection fatality rate fell to 0.3% by end of 2020


As of September 2

5,049,465 children have tested positive

252,000 cases were added the past week

Largest number of child cases in a week ever

Since the pandemic began, children, 15.1% of total cumulated cases

Week ending September 2nd, 26.8% of reported weekly COVID-19 cases

2,400 children were hospitalized nationwide (highest in pandemic)

Hospitalizations (24 states and NYC reported)

Children ranged from 1.6%-4.1% of total cumulated hospitalizations

0.1%-1.9% of all their child COVID-19 cases resulted in hospitalization

Mortality (45 states)

Children were 0.00%-0.27% of all COVID-19 deaths

(7 states reported zero child deaths)

0.00%-0.03% of all child COVID-19 cases resulted in death

Vaccination in children

Half of children ages 12 to 15 have received at least one vaccine dose

58 percent for 16- and 17-year-olds

Anthony Fauci, National Institute of Allergy and Infectious Diseases

We’ve got to get the school system masked,

in addition to surrounding the children with vaccinated people

That’s the solution

Los Angeles mandates today

Soon mandate vaccination for school attendance

600,000 would have to get their first shot by Oct. 3

Second shot by the end of October

(LA counts since last month)

Pascal Soriot, AstraZeneca chief executive on Booster doses


UK is still "a few weeks away" from being able to decide

Moving too quickly to boost across the entire adult population will deprive us of these insights,

leaving this important decision to rest on limited data

NHS resource implications

NHS is ‘ready to go’

Philip Dormitzer, Pfizer’s chief scientific officer

Encouraged booster shots

Dismissed criticism that his company should have produced a more potent vaccine

Professor Sarah Gilbert


UK, 3.8 million people classed as clinically extremely vulnerable

In people who have been vaccinated and have had the two doses,

they will be well protected against disease that is severe enough to put them in hospital and against death

And there are unfortunately some people with particular health conditions that mean they just don’t respond to a vaccine

and they are going to have to make sure that they are protected, probably by shielding again,

if there is a lot of spread of the virus


we are advising clinically extremely vulnerable people, as a minimum, to follow the same guidance as everyone else

you may wish to think particularly carefully about additional precautions you might wish to continue to take


Removing all remaining restrictions by the end of this month
