• For a non-immune pregnant woman after significant exposure, oral aciclovir or valaciclovir is the UKHSA first-choice post-exposure prophylaxis.
• Antiviral prophylaxis is given from day 7 to day 14 after exposure rather than immediately after contact.
• The recommended aciclovir prophylaxis dose is 800 mg orally four times daily.
• The recommended valaciclovir prophylaxis dose is 1000 mg orally three times daily.
• VZIG may be used when antivirals are contraindicated or cause intolerable adverse effects and is effective when administered up to 10 days after contact.
• For continuous exposure, the 10-day VZIG window is counted from the appearance of the rash in the index case.
• A susceptible woman who receives VZIG should be regarded as potentially infectious from days 8–28 after exposure; without VZIG the corresponding interval is days 8–21.
• After a further significant exposure without seroconversion, another antiviral course can be prescribed from day 7 after the new exposure.
• If VZIG was previously used, it can be repeated when the subsequent exposure occurs at least 3 weeks after the previous VZIG dose.
• VZIG injection-site pain and erythema may occur; the cited risk of anaphylaxis is below 0.1%.
