US COVID-19 data has never been good enough

When American consultants first began to fret that COVID-19 vaccines weren’t working fairly as properly towards delta as they did towards earlier coronavirus strains, they didn’t have a lot home data to go on. The Facilities for Illness Management and Prevention was solely gathering data on post-vaccination COVID-19 circumstances in the event that they led to hospitalization or loss of life — the company wasn’t doing big-picture tracking of COVID-19 in vaccinated folks. Just a few states and counties had been gathering and publicizing that data.

The CDC was doing a little evaluation, nevertheless it wasn’t sharing the data rapidly, frustrating experts who hoped for a extra dynamic image of how the delta variant was affecting vaccinated folks. The company lastly launched some data this week as a part of the justification for pushing booster doses of the COVID-19 vaccine, however the scope was nonetheless restricted and got here too late.

“It’s not acceptable how lengthy it takes for this data to be made out there,” a senior CDC official told The Washington Post. For probably the most half, US consultants needed to depend on vaccine data from different international locations: Israel, Canada, the UK.

Data, or lack thereof, has been one of many greatest challenges within the US COVID-19 response. From the early days of the outbreak, well being departments have struggled to collect information on circumstances, and infrequently solely had delayed and incomplete data. Most medical trials investigating COVID-19 treatments had been small and couldn’t ship conclusive solutions.

A part of the issue was that the US has a fragmented public well being system, and data is siloed off in particular person hospitals. Locations with nationwide well being techniques, just like the UK, had been in a greater place to know big-picture tendencies by the pandemic — its Nationwide Well being Service was capable of run a multisite clinical trial to have a look at COVID-19 therapies, which finally recognized therapies that saved lives.

Over 18 months later, the issues within the US persist. Officers don’t have a good grasp on the place and the way COVID-19 is spreading in sure teams, former Meals and Drug Administration Commissioner Scott Gottlieb outlined on Twitter. The CDC isn’t geared up to gather real-time data, he notes. That constrains the nation’s response.

Now, these issues are making it more durable to know the dynamics of coronavirus infections from the delta variant in vaccinated folks within the US. Delta has solely been the dominant coronavirus variant within the US for round two months, so it might take a while for the patterns to emerge. However officers are shifting ahead with booster plans primarily based solely on the restricted data they’ve now. Hopefully, the data will finally meet up with their actions.
