Revenue in the segment is expected to rise 0-4%, after dipping 2% to £7bn in 2020.
It’s missing out on huge potential for revenue upside, considering that Pfizer forecast its jab to generate US$15bn (£11bn) of sales.
While the Medicago formulation is currently at the final stage of clinical trials, the Sanofi one is back into the lab after some disappointing test results, so it will not be market-ready until the fourth quarter of 2021.
Earlier on Wednesday, the pharma giant revealed its third COVID-19 vaccine partnership with German biopharma CureVac to focus on mRNA formulations to target variants of the virus as they emerge.
In the current financial year, pharmaceutical revenue is also expected to grow 0-4% while consumer healthcare will advance 1-7%.
GSK is also to announce a new dividend policy, implemented from 2022 onwards, that will “deliver competitive and attractive returns informed by appropriate earnings pay-out ratios” but will be lower than the current value.
The drugmaker added it is on track to separate two new standalone Biopharma and Consumer Healthcare companies in 2022 to save £300mln annually while it also made £1.1bn from divestments.
For the year to December 31, shareholders will receive a final dividend of 80p per share.
Turnover in the period inched up 1% to £34bn, driven by a 12% in pharmaceuticals and offset by a 3% dip in pharmaceuticals and lower vaccine revenue.

"The pandemic has also negatively affected demand for some traditionally more reliable Pharmaceutical products, like antibiotics. That would be manageable were it not for the long drag of patent losses in key asthma products – offsetting much of the progress in newer pharmaceutical products."
"GSK is a company in transition – and by 2022 will be starting life as two separate companies. While we haven’t always supported breaking the business up, we now think the move can’t come soon enough. GSK in its current iteration seems to be struggling to set out a clear vision of what it offers investors. Hopefully its successor companies are a little more streamlined.”
Shares dropped 5% to 1,301.85p on Wednesday after lunch.
