Moderna MRNA released preliminary data from its late-stage trials, which showed that its vaccine candidate was 94.5% effective against the coronavirus. The news was followed by promising late-stage trial results last week from the U.S. drugmaker Pfizer PFE and German biotech firm BioNTech for their COVID-19 vaccine candidate. The data showed that the candidate was more than 90% effective in preventing the disease. The slew of positive data has instilled strong optimism into the economy which was hit-hard by the pandemic.More Gains Ahead?Currently, VTWO has a Zacks ETF Rank #2 (Buy) with a Medium risk outlook, suggesting that the outperformance could continue in the months ahead.
