Publications distort misleading analysis of COVID-19 vaccine safety data

An summary of a number of the questions requested throughout a v-safe check-in. Screenshot taken from a CDC video promote the v-safe instrument.

“It does not have the extent of element and granularity to precisely assess whether or not these occasions are causally linked. And you realize, there is no comparability group there, everybody in v -safe is vaccinated, and due to this fact it’s unattainable to find out whether or not a vaccine induced a selected adversarial occasion based mostly solely on the v-safe information,” Belongia instructed us.

The system is a part of a larger early warning reporting system which permits specialists to watch the security of vaccines. Belongia and different specialists say v-safe has limits. However he says the instrument has been helpful for observing widespread unwanted effects of vaccines resembling ache on the injection web site, headache, muscle aches or fever.

“And what we’re seeing is essentially per what’s been seen in scientific trials.: this these signs are quite common, they’re gentle to reasonable, they resolved in two to 3 days, so there’s actually nothing stunning about that,” he mentioned.

Knowledge collected by v-safe will not be publicly obtainable in the identical approach as information from different methods just like the The vaccine adverse event reporting system is. As an alternative, info is launched to the general public by a number of research that analyze v-safe information within the CDC Morbidity and Weekly Mortality Report and other journals, and in displays to the Advisory Committee on Immunization Practices. Based on the CDC, v-safe information has been offered at 11 conferences for the reason that vaccines had been rolled out – in December 2020; January, March, June, September and October 2021; and in January, April, May, June and September 2022.

Some finds of these studies are that the second dose of the first collection induced extra members to report gentle, non permanent signs or being unable to carry out regular exercise, and that the second booster cause fewer anticipated unwanted effects, resembling ache on the injection web site, than the primary. Based on the CDC, when COVID-19 vaccines started being given, v-safe was essential for identifying early reports a severe allergic response which not often happens after vaccinations.

A research, revealed within the Lancet Infectious Ailments in March, analyzed v-safe reviews between December 14, 2020 and June 14, 2021, after administration of the Pfizer/BioNTech and Moderna COVID-19 vaccines. Based on his findings, Less than 1% of v-safe customers reported receiving medical care throughout the first week after receiving a major collection dose of both vaccine, and a really small proportion (0.2% or much less) reported an emergency room go to or hospitalization. Once more, even these medical visits should not essentially attributable to the vaccine and might be coincidental.

ICAN’s Deceptive Evaluation

Knowledgeable Consent Motion Community is a Texas-based group based by Del Bigtree, a anti-vaccination activist. The group filed a number of vaccine lawsuits in opposition to the CDC, the Meals and Drug Administration and the Nationwide Institutes of Well being. ICAN sued the CDC in December 2021and once more in May 2022following FOIA requests for all information submitted to v-safe since January 1, 2020. The v-safe program didn’t start till after the COVID-19 vaccines had been cleared in December 2020.

In August, the CDC agreed publish information collected from greater than 10 million v-safe members on its web site by September 30. The database would cowl reviews submitted between December 14, 2020 and July 31, 2022 and omit any private identifiers. The company mentioned Reuters “technical and administrative” issues prevented it from publishing the information on time. As an alternative, the CDC transmitted the information on to ICAN, which published its personal evaluation on October 3.

On its web site, ICAN does not clarify the strategies used for its evaluation. However he mentions that the information is restricted to the ten million v-safe customers and the pre-filled fields verified by them, not info that customers can add in textual content containers. Based on the group’s dashboard, the information is drawn from data that occurred as much as a 12 months after a vaccine dose. The group too published 5 downloadable recordsdata with uncooked v-safe information.

FactCheck.org has contacted Aaron Siri and different Siri & Glimstad representatives, who filed the FOIA dispute for ICAN, however we’ve got not heard again from them. We additionally tried to entry the uncooked information offered, however we had been unable to open the most important file containing info relating to well being checks.

We had been capable of entry one of many recordsdata containing signs and well being impacts, which included 116,294 reviews. Of those reviews, 1,046, or 0.9%, had been medical care reviews of any variety, and this included a number of reviews from the identical individual over time. Of those, solely seven concerned hospitalizations, together with two for a similar individual for 2 consecutive days.

Belongia, the vaccine security knowledgeable, shared with us the figures supplied by ICAN, together with the more than 780,000 users who’ve declared that they want medical consideration of any variety, are “uninterpretable”.

“We do not know what the background price is within the v-safe inhabitants. What would that quantity have been in a gaggle of people that had not obtained the vaccine? ” he mentioned.

Since well being issues, together with hospitalizations, happen daily within the inhabitants, it isn’t unusual for them to come up after vaccination for causes unrelated to the vaccine. For this reason you will need to see if a selected occasion happens extra often after vaccination, which might point out an issue.

The evaluation doesn’t point out how lengthy after vaccination a consumer wanted medical consideration, however included responses as much as a 12 months after vaccination, which might clarify the distinction between the ICAN figures and the information revealed by the CDC. Siri Told Reuters that ICAN thought it was vital to look past one week as a result of some potential vaccine-related unwanted effects might present up weeks after vaccination. However most unwanted effects happen shortly after vaccination, so together with longer intervals would come with extra occasions which are unrelated to the vaccine.

A consumer might have seen a physician for a very totally different motive six months after a shot and, in the event that they observe v-safe’s directions accurately, will report this to the system. This consumer would obtain a follow-up name from v-safe, for the company to get extra info. However as we mentioned, v-safe doesn’t have the power to know whether or not a selected occasion, together with hospitalization, was attributable to the vaccine or not.

“And so to reply questions like that, when it comes to relative danger, you want one thing just like the Vaccine Security DataLink or VSD, which makes use of the medical data of thousands and thousands of individuals throughout the nation and the data vaccination to implement scientifically legitimate research to find out if there’s an elevated post-vaccination danger for specific adversarial occasions,” Belongia mentioned, referring to a network of nine integrated health organizationstogether with his personal, which actively displays vaccine security.

“What we are literally seeing within the information is the precise reverse of what’s recommended by teams like ICAN – these vaccines are very protected. With, you realize, some only a few recognized exceptions,” Belongia mentioned. “However total, it’s extremely clear that the advantages of vaccines far outweigh the dangers.”
