Healthcare professionals discuss vaccines in the fight against Omicron, with Pfizer vaccine the most discussed


Pfizer has established itself as the most mentioned pharmaceutical company among healthcare professionals, often discussed in relation to its COVID-19 vaccine.

CREATION.co has used its cutting-edge Pinpoint® database of more than 3 million healthcare professionals’ (HCPs) social media profiles to rank the top 50 pharmaceutical companies mentioned by healthcare professionals (HCPs) on Twitter.

Based on 35,141 healthcare professional authored tweets from 12,497 individual HCPs mentioning a Top 50 Pharmaceutical company, as identified by CREATION.co, Pfizer received 26,367 mentions which is six times more than AstraZeneca in second place.

According to CREATION.co’s tracking, Pfizer has been the most discussed pharmaceutical company among HCPs for a number of months now.

News about COVID-19, with the Omicron variant continuing to affect life in the UK, continues to drive HCPs’ discussions about pharmaceutical companies. The effectiveness of each company’s drugs against coronavirus is particularly well discussed, with HCPs’ sharing trial data regarding the efficacy of the Pfizer vaccine. The new social media analysis has shown Regeneron has been widely panned for its poor performance.

The most shared links by HCPs were about the usefulness of the Pfizer vaccine against the new Omicron variant:

  1. Study results produced by Alex Sigal of Sigal Lab regarding the neutralization of Omicron using the Pfizer vaccine.
  2. A press release by Pfizer about the ability of its vaccine to neutralize Omicron.
  3. Study results regarding T cell responses against Omicron. 

Conversely, Regeneron climbed into the top five most talked about pharmaceutical companies due to news about their monoclonal antibodies ineffectiveness against the Omicron variant. HCP conversations involved sharing the information surrounding the monoclonal antibodies, as well as frustration about the unavailability of the antibodies given the severity of the pandemic.

Commenting on the analysis, Daniel Ghinn, CEO and Founder of CREATION.co said:

“The level of mentions by HCPs of pharmaceutical companies shows the debate regarding the merits of each COVID-19 vaccine is not going away.

“Pfizer is by far and away the most discussed pharmaceutical company among HCPs often in relation to the effectiveness of its vaccine. Volume of mentions does not necessarily mean a warm reception, as Regeneron is discovering following the public fallout over the performance of its drugs.

“Our analysis ought to remind the drug companies that HCPs will be paying attention to every trial and test and will not be hesitant in coming forward about how they perceive the results.”
