Other identifiable secondary causes of hypertension~10. Myocardial infarction, unstable angina pectoris, or a cerebrovascular accident within 6 months of Screening.~11. Bradycardia \<50 beats per minute at rest in the supine position prior to randomisation.~12. Have sick sinus syndrome or second or third degree atrioventricular block, chronic atrial fibrillation or recurrent atrial tachyarrhythmia (including paroxysmal atrial tachycardia), history of recurrent ventricular tachycardia, or symptomatic bradycardia.~13. Implanted pacemakers or cardioverter defibrillator.~14. Haemodynamically significant valvular heart disease.~15. History of renal dysfunction and/or estimated glomerular filtration rate \<60 mL/min/1.73 m2.~16. Diagnosis or recurrence of malignancy within the past 3 years, with the exception of basal cell carcinoma of the skin or in situ carcinoma of the cervix.~17. Sleep apnea unless a recent (within 30 days of Screening) sleep study demonstrates no recordings of arterial oxygen saturation (SaO2) \<90%, treated or untreated, at any time during the Screening Period.~18. Perform alternating shift or night work.~19. Not on stable doses of all concomitant medications for a minimum of 4 weeks prior to Screening, and subjects treated with any of the following prohibited medications:~    * Oral corticosteroids within 3 months of Screening.~   * Acetylsalicylic acid in excess of 325 mg per day.~   * Chronic stable or unstable use of non-steroidal anti-inflammatory drugs (NSAIDs) other than acetylsalicylic acid is prohibited.~   * Selective serotonin reuptake inhibitors or selective serotonin norepinephrine reuptake inhibitors, if a subject is not compliant with the medication and/or has not been receiving a stable dose for at least 3 months prior to Screening.~   * Tricyclic antidepressants, if a subject is not compliant with the medication and/or has not been receiving a stable dose for at least 3 months prior to Screening.~   * Any angiotensin vaccine, including prior exposure to ATV.~20. Have participated in a clinical study involving another investigational drug or device within 4 weeks of Screening.~21. Any concomitant condition that, in the opinion of the investigator, may adversely affect the safety and/or efficacy of the study drug or severely limit the subject's ability to complete the study (eg, disabling or terminal illness, mental disorders).~22. Any major contraindication to stopping antihypertension medications for a period of up to 14 weeks.~23. Previous exposure to CoVaccine HT adjuvant, or other keyhole limpet haemocyanin-containing vaccines.~24. Previous serious reaction to a vaccine, such as angioedema or anaphylaxis.~25. Known history of drug and/or alcohol abuse and those known to be hepatitis positive.
