China’s Sinovac Covid-19 vaccine received the most media attention in January as compared to other vaccine suppliers such as Moderna, Sputnik, AstraZeneca and Pfizer.
As seen in the news dependency among the five Covid-19 vaccine companies, Moderna was previously leading in early January but was later defeated by Sinovac on the 11th.
Sinovac’s news exposure skyrocketed until the 13th and 14th, reaching about 75 news each day.
However, Sinovac’s news exposure declined on the 15th but was still leading among the other vaccine companies.
On the 23rd, Moderna’s news coverage slightly increased but was surpassed again by Sinovac on the 25th and soared higher on the 26th, exceeding 50 news that day.
Recently, Malaysia has announced that they have inked a deal with Russia’s Sputnik to procure their Covid-19 vaccines but was still not enough to surpass Sinovac’s news exposure.
Despite Sinovac’s low efficacy rate at 50.4% as compared to Pfizer’s 95% rate and Moderna’s 94.5% rate, Sinovac still obtained the most positive news sentiments.
Apart from that, both Pfizer and Moderna received more negative news sentiments although their efficacy rate is above 70%.
On a side note, Minister of Science, Technology, and Innovation Khairy Jamaluddin is the top influencer for the Sinovac topic and was ranked the third influencer for both the Sputnik and Pfizer topic.
